    Loads Due to Controls at Transonic and Low Supersonic Speeds (1957)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: Some results of recent experimental investigations at supersonic and transonic speeds are presented to show the present status in the estimation of load distributions on controls and adjacent wing surfaces resulting from the deflection of flap controls and spoiler controls. The results indicate that the development of methods for predicting loads associated with controls has not kept pace with the acquisition of experimental data. At low supersonic speeds sweeping the hinge line induces strong three-dimensional-flow characteristics which cannot be treated by the simplified methods previously developed for controls without sweep. At transonic speeds the estimation of loads associated with controls must usually be dependent upon experimental information inasmuch as the latest attempts to predict chordwise and spanwise loadings have met with only limited success.

    Boundary-Layer-Transition and Heat-Transfer Measurements from Flight Tests of Blunt and Sharp 50 Degree Cones at Mach Numbers from 1.7 to 4.7 (1957)
    In:  CASI
    Details
    Publication Date: 2019-05-30
    Description: Boundary-layer-transition and heat-transfer measurements were obtained from flight tests of blunt and sharp cones having apex angles of 50 deg. The test Mach number range was from 1.7 to 4.7, corresponding to free-stream Reynolds numbers, based on cone base diameter, of 18. 3 x 10(exp 6) and 32.1 x 10(exp 6), respectively. Transition on both models occurred at a local Reynolds number of 1 x 10(exp 6) to 2 X 10(exp 6) based on distance from the stagnation point. Transition Reynolds numbers based on momentum thickness were between 320 and 380 for the blunt cone. The model surface roughness was 25 rms microinches or greater. Turbulent heat transfer to the conical surface of the blunt cone at a Mach number of 4 was 30 percent less than that to the surface of the sharp cone. Available theories predicted heat-transfer coefficients reasonably well for the fully laminar or turbulent flow conditions.

    A Simplified Theory of Porous Wall Cooling (1947)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: The rate of heat transfer between a fluid stream in turbulent flow and a smooth, solid wall is largely controlled by the relatively high resistance of the laminar sublayer next to the wall. Although this laminar layer ii extremely thin, heat can be transferred through it only by molecular diffusion. Hence the resistance of this layer is very much greater than for a layer the same thickness farther out in the stream where turbulent exchange is the controlling factor. The thickness of the laminar layer is difficult to define precisely, since there is a gradual transition to the turbulent flow outside, but for the usual scale of many engineering applications almost half the temperature difference between the fluid and the wall occurs in a layer of a few thousands of an inch in thickness. When the wall is made of porous material and a coolant gas is forced through the wall into the stream, it has been found that a very small flow rate of the coolant is remarkably effective in keeping the wall at a low temperature. The coolant flow rate required is such as to give an average velocity normal cooling wall of the order of 1 per cent of the main stream velocity. This flow rate is so low that clearly the injected gas must act as an insulator rather than as a normal coolant. Because of its relatively low velocity, the injected gas can have very little influence on heat convection or momentum transfer in the turbulent stream, and its effect must be confined to the laminar sublayer. The possible influence of the coolant flow on the thickness of the laminar layer will be discussed in Section V.

    Free-Flight Skin Temperature and Pressure Measurements on a Slightly Blunted 25 Deg Cone-Cylinder-Flare Configuration to a Mach Number of 9.89 (1957)
    In:  CASI
    Details
    Publication Date: 2019-06-27
    Description: Skin temperatures and surface pressures have been measured on a slightly blunted cone-cylinder-flare configuration to a maximum Mach number of 9.89 with a rocket-propelled model. The cone had a t o t a l angle of 25 deg and the flare had a 10 deg half-angle. Temperature data were obtained at eight cone locations, four cylinder locations, and seven flare locations; pressures were measured at one cone location, one cylinder location, and three flare locations. Four stages of propulsion were utilized and a reentry type of trajectory was employed in which the high-speed portion of flight was obtained by firing the last two stages during the descent of the model from a peak altitude of 99,400 feet. The Reynolds number at peak Mach number was 1.2 x 10(exp 6) per foot of model length. The model length was 6.68 feet. During the higher speed portions of flight, temperature measurements along one element of the nose cone indicated that the boundary layer was probably laminar, whereas on the opposite side of the nose the measurements indicated transitional or turbulent flow. Temperature distributions along one meridian of the model showed the flare to have the highest temperatures and the cylinder generally to have the lowest. A maximum temperature of 970 F was measured on the cone element showing the transitional or turbulent flow; along the opposite side of the model, the maximum temperatures of the cone, cylinder, and flare were 545 F, 340 F, and 680 F, respectively, at the corresponding time.

    The Turbulent Flow in Diffusers of Small Divergence Angle (1947)
    In:  CASI
    Details
    Publication Date: 2019-07-11
    Description: The turbulent flow in a conical diffuser represents the type of turbulent boundary layer with positive longitudinal pressure gradient. In contrast to the boundary layer problem, however, it is not necessary that the pressure distribution along the limits of the boundary layer(along the axis of the diffuser) be given, since this distribution can be obtained from the computation. This circumstance, together with the greater simplicity of the problem as a whole, provides a useful basis for the study of the extension of the results of semiempirical theories to the case of motion with a positive pressure gradient. In the first part of the paper,formulas are derived for the computation of the velocity and.pressure distributions in the turbulent flow along, and at right angles to, the axis of a diffuser of small cone angle. The problem is solved.

    Effect of Some External Crosswise Stiffeners on the Heat Transfer and Pressure Distribution on a Flat Plate at Mach Numbers of 0.77, 1.39, and 1.98. Coord. No. AF-AM-69 (1957)
    In:  CASI
    Details
    Publication Date: 2019-07-12
    Description: The heat transfer and pressures on the surfaces of several flat-plate models with various external crosswise stiffener arrangements are presented. The tests were made in a free jet at Mach numbers of 0.77, 1.39, and 1.98 for Reynolds numbers of 3 x 10(exp 6), 7 x 10(exp 6), and 14 x 10(exp 6), respectively, based on a length of 1 foot. The addition of external crosswise stiffeners to the flat-plate models caused large pressure and heat-transfer variations on the surfaces of the models.

    Effect of Air-Flow Distribution and Total-Pressure Loss on Performance of One-Sixth Segment of Turbojet Combuster (1947)
    In:  CASI
    Details
    Publication Date: 2019-07-12
    Description: An investigation has been conducted on a one-sixth segment of an annular turbojet combustor to determine the effects of modification in air-flow distribution and total-pressure loss on the performance of the segment. The performance features investigated during this series of determinations were the altitude operational limits and the temperature-rise efficiency. Altitude operational limits of the combustor segment, for the 19XB engine using the original combustor-basket design were approximately 38,000 feet at 17,000 rpm and 26,000 feet at 10,000 rpm. The altitude operational limits were approximately 50,000 feet at 17,000 rpm and 38,000 feet at 10,000 rpm for a combustor-basket design in which the air-passage area in the basket was redistributed so as to admit gradually no more than 20 percent of the air along the first half of the basket. In this case the total pressure loss through the combustor segment was not appreciably changed from the total-pressure loss for the original combustor basket design. Altitude operational limits of the combustor segment for the 19XB engine were above 52,000 feet at 17,000 rpm and were approximately 23,000 feet at 10,000 rpm for a combustor-basket design in which the distribution of the air-passage area in the basket was that of the original design but where the total-pressure loss was increased to 19 times the inlet reference kinetic pressure at an inlet-to-outlet density ratio of 2.4. The total-pressure loss for the original design was 14 times the inlet kinetic reference pressure at an inlet-to-outlet density ratio of 2.4.

    The Principles of Turbulent Heat Transfer (1957)
    In:  CASI
    Details
    Publication Date: 2019-08-13
    Description: The literature on turbulent heat transfer has in the course of years attained a considerable volume. Since this very complicated problem has not as yet found a complete solution, further studies in this field may be expected. The heat engineer must therefore accomodate himself to a constantly increasing number of theories and formulas. Since the theories generally start from hypothetical assumptions, and since they contain true and false assertions, verified knowledge and pure suppositions often being intermingled in a manner difficult to tell them apart, the specialist had difficulty in forming a correct evaluation of the individual studies. The need therefore arises for a presentation of the problem of turbulent heat transfer which is not initially bound by hypothetical assumptions and in which uninvestigated can be clearly distinguished form each other. Such a presentation will be given in the present treatment. Brief remarks with regard to the development of the theory of local heat transfer are included.

    Laboratory Report on the Investigation of the Flow around Two Turbine-Blade Profiles using the Interferometer Method (1947)
    In:  CASI
    Details
    Publication Date: 2019-07-11
    Description: At the request of the Junkers Aircraft and Engine Construction Company, Engine Division, Dessau Main Plant, an investigation was made using the interferometer method on the two turbine-blade profiles submitted. The interferometer method enables making visible the differences in density and consequently the boundary layers that develop when a flow is directed on the profile. Recognition of the points on the profile at which separation of flow occurs is thus possible. By means of the interference photographs the extent of the dead-water region may be ascertained. The size of the dead-water region provides evidence as to the quality of the flow and allows a qualitative estimate of the amount of the flow losses. Interference photographs thus provide means of judging the utility of profiles under specific operating conditions and provide suggestions for possible changes of profile contours that might help to improve flow relations. Conclusions may be drawn concerning the influence of the blade-spacing ratio, the inlet-air angle, and the connection between the curvature of the profile contour and the point of separation of the flow from the profile surface.

    Measurements of Heat Transfer and Boundary-Layer Transition on an 8-Inch-Diameter Hemisphere-Cylinder in Free Flight for a Mach Number Range of 2.00 to 3.88 (1957)
    In:  CASI
    Details
    Publication Date: 2019-07-11
    Description: Measurements of aerodynamic heat transfer have been made along the hemisphere and cylinder of a hemisphere-cylinder rocket-propelled model in free flight up to a Mach number of 3.88. The test Reynolds number based on free-stream condition and diameter of model covered a range from 2.69 x l0(exp 6) to 11.70 x 10(exp 6). Laminar, transitional, and turbulent heat-transfer coefficients were obtained. The laminar data along the body agreed with laminar theory for blunt bodies whereas the turbulent data along the cylinder were consistently lower than that predicted by the turbulent theory for a flat plate. Measurements of heat transfer at the stagnation point were, in general, lower than the theory for stagnation-point heat transfer. When the Reynolds number to the junction of the hemisphere-cylinder was greater than 6 x l0(exp 6), the transitional Reynolds number varied from 0.8 x l0(exp 6) to 3.0 x 10(exp 6); however, than 6 x l(exp 6) when the Reynolds number to the junction was less, than the transitional Reynolds number varied from 7.0 x l0(exp 6) to 24.7 x 10(exp 6).

A discontinuous change of state is therefore connected with the condensation; schlieren photographs of supersonic flows in two-dimensional Laval nozzles show two intersecting oblique shock fronts that in the case of high humidities may merge near the point of intersection into one normal shock front.

    Equations for Adiabatic but Rotational Steady Gas Flows without Friction (1947)
    In:  CASI
    Details
    Publication Date: 2019-07-11
    Description: This paper makes the following assumptions: 1) The flowing gases are assumed to have uniform energy distribution. ("Isoenergetic gas flows," that is valid with the same constants for the the energy equation entire flow.) This is correct, for example, for gas flows issuing from a region of constant pressure, density, temperature, end velocity. This property is not destroyed by compression shocks because of the universal validity of the energy law. 2) The gas behaves adiabatically, not during the compression shock itself but both before and after the shock. However, the adiabatic equation (p/rho(sup kappa) = C) is not valid for the entire gas flow with the same constant C but rather with an appropriate individual constant for each portion of the gas. For steady flows, this means that the constant C of the adiabatic equation is a function of the stream function. Consequently, a gas that has been flowing "isentropically",that is, with the same constant C of the adiabatic equation throughout (for example, in origination from a region of constant density, temperature, and velocity) no longer remains isentropic after a compression shock if the compression shock is not extremely simple (wedge shaped in a two-dimensional flow or cone shaped in a rotationally symmetrical flow). The solution of nonisentropic flows is therefore an urgent necessity.

The measurements were made in a Parr oxygen-bomb calorimeter, and the combustion was believed to be 98 percent complete. The estimated net-heat of combustion for complete combustion would therefore be 20,850 +/- 150 Btu per pound.

    Description: It is known that compression shocks which lead from supersonic to subsonic velocity cause the flow to separate on impact on a rigid wall. Such shocks appear at bodies with circular symmetry or wing profiles on locally exceeding sonic velocity, and in Laval nozzles with too high a back pressure. The form of the compression shocks observed therein is investigated.

    Effects of Compressibility on the Flow Past Thick Airfoil Sections (1947)
    In:  CASI
    Details
    Publication Date: 2019-07-11
    Description: Six, 3-inch-chord symmetrical airfoil sections having systematic variations in thickness and thickness location were tested at Mach numbers near flight values for propeller-shank sections. The tests, the results of which are presented in the form of schlieren photographs of the flow past each model and pressure-distribution charts for two of the model, were performed to illustrate the effects of compressibility on the flow past thick symmetrical airfoil sections. Representative flow photographs indicated that at Mach numbers approximately 0.05 above the critical Mach number a speed region was reached in which the flow oscillated rapidly and the separation point and the location of the shock wave were unstable. Fixing the transition on both surfaces of the airfoil was effective in reducing these rapid oscillations. The pressure distributions showed that the section normal-force coefficients for thick airfoils were very erratic at subcritical speeds; at supercritical speeds the section normal-force coefficients for the thick airfoils became more regular. Drag coefficients showed that considerable drag decreases can be expected by decreasing the model thickness ratio.

    Description: As a turbine rotor turns, the blades traverse the wake zones of the nozzle vanes. A periodic fluctuation of the pressure distribution around the circumference of the rotor blade is therefore caused. It was desired to investigate quantitatively this effect. At the same time, the magnitude of the force acting upon one profile of the rotor-blade lattice at various positions of this lattice relative to the nozzle lattice was to be determined.

    The Effect of Solid Admixtures on the Velocity of Motion of a Free Dusty Air Jet (1957)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: In dusty air flows occurring in industrial practice in transport by air pressure of friable materials, in the drying, annealing, and so forth, of a pulverized solid mass in suspension, and in other processes, the concentration of solid particles usually has a magnitude of the order of 1 kg per 1 kg of air. At such a concentration, the ratio of the volume of the particles to the volume of the air is small (less than one-thousandth part). However, regardless of this, the presence of a solid admixture manifests itself in the rules for the velocity distribution of the air in a dusty air flow. As a result, the rules of velocity change are different for clean and for dusty air flows. The estimation of the influence of the admixture on the velocity of the motion of the flow presents a definitive interest. One of the attempts to estimate that influence on the axial velocity of a free axially symmetrical jet with admixtures was made by Abramovich. Abramovich assumed beforehand that the fine particles of the admixture in the jet are subject to the motion of the air (that is, that the velocity of the admixture is approximately equal to the local velocity of the air); he then took as the basis of his considerations, in solving the problem, the condition that the amount of motion of the two-phase jet must be constant.

    The Effect of Turbulence on the Flame Velocity in Gas Mixtures (1947)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: The present report deals with the effect of turbulence on the propagation of the flame. Being based upon experiments with laminar as well as turbulent Bunsen flames, both the physico-chemical and the hydro-dynamical aspects of the problem are analyzed. A number of new deductions, interesting from the point of view of engine combustion and other very rapidly changing flame reactions, are made.

    Notes: Zunächst wird über Untersuchungen berichtet, bei denen Wärmeübergang, Druckabfall sowie die Temperatur- und Geschwindigkeitsverteilung im rauhen Rohr gemessen wurden. Die Ergebnisse konnten allgemeingültig dargestellt und theoretisch begründet werden. Ferner wird auf wirtschaftliche Fragen und den Einfluß von Schmutzschichten im Rohr auf den Wärmeübergang eingegangen. Bei Untersuchungen an einem linsenförmigen Rohr und außen beheizten Ringspalten stand die Frage nach dem maßgebenden gleichwertigen Durchmesser im Vordergrund. Weiterhin wurde der Wärmeübergang zwischen staubhaltiger Luft und einer Kugelschüttung gemessen; dabei war kein merklicher Einfluß des Staubgehaltes zu erkennen. Sehr eingehend wurde schließlich das Strömungsverhalten von Rieselfilmen untersucht. Die kritische Reynolds-Zahl konnte zu 400 bestimmt werden. Außerdem wurden die Höhe der Wellen, die Filmdicke und die Wandschubspannung gemessen, so daß auch das Widerstandsgesetz der welligen Filmströmung angegeben und eine Näherungstheorie für den Wärmeübergang aufgestellt werden konnte.

    Notes: Aufbereitung ist angewandte Physik, physikalische Technologie und bergmännische Verfahrenstechnik. In der Verbrauchsgüter- und Genußmittelindustrie werden die gleichen Grundverfahren angewandt wie bei der Aufbereitung der Erze, der Kohlen, der Steine und Erden. Zweckentsprechende Kombinationen dieser Grundverfahren führen zur erfolgreichen Aufbereitung bergmännisch gewonnener Haufwerke. Die gleichen Grundverfahren und Grundvorgänge verbinden den Verfahrenstechniker mit dem Aufbereiter und veranlassen ihn, die Aufbereitung als „bergmännische Verfahrenstechnik“ zu kennzeichnen.

    Notes: Physikalische Größen können meist auf verschiedene Weise gemessen werden. Für die Standmessung von Flüssigkeiten gibt es zahlreiche meßtechnische Möglichkeiten. Die meisten von ihnen sind einfach und gut übersehbar, und dies dürfte einer der Gründe sein, weshalb sie im Schrifttum wenig behandelt und beachtet werden. Im Zusammenhang mit der Regelung weisen sie aber interessante Kennzeichen auf, die eine eingehendere Darstellung rechtfertigen.

    Notes: Die Anwendung der elektrischen Mikrowaage zur Registrierung von Staubgehalten ist seit mehreren Jahren Gegenstand intensiver Entwicklungsarbeit. Nachdem eine für Raumstaubmessung geeignete Anordnung vorlag, wurde die Staubgehaltsmessung in heißen Abgasen in Angriff genommen. Mit einem Versuchsmodell sind Versuche in industriellen Anlagen vorgenommen worden. Diese haben gezeigt, daß der eingeschlagene Weg grundsätzlich gangbar ist. Ein zweites Versuchsgerät, das zur Zeit erprobt wird, verspricht, sich in schrittweiser Verbesserung zum betriebssicheren Registriergerät zu entwickeln.

    Notes: Die elektrostatische Aufladung von gereinigtem n-Heptan wurde in Abhängigkeit von Art und Menge verschiedener Zusätze (Alkohole, Peroxyde, Fettsäuren, Ester, Amine, Mercaptane, Silicone) gemessen. Der Aufladestrom war in dem Bereich von 10-18 bis 10-11Ω-1 cm-1 der Leitfähigkeit des Systems proportional. Die elektrostatische Aufladung technischer Kohlenwasserstoff-Fraktionen wurde im wesentlichen durch Oxvßationsprodukte hervorgerufen.

    Notes: Heute bekannte Anwendungsgebiete für energiereiche Strahlung werden zusammengestellt und einige Grundlagen erörtert. Die Bestrahlung von pharmazeutischen und medizinischen Produkten zur Sterilisation, die Behandlung von Lebensmitteln und die Härtung von thermoplastischen Kunststoffen werden bereits erfolgreich ausgenutzt. Gesichtspunkte für die technische Ausführung werden angegeben und ein brauchbarer Teilchen-Beschleuniger im Vergleich zu den vorhandenen Möglichkeiten besprochen. Die erweiterte Anwendung von energiereicher Strahlung in der Verfahrenstechnik erfordert noch eingehende Forschungsarbeit.

    Notes: Zur Inbetriebnahme von Kugelgasbehältern wird nach der Arbeitsweise des Gaswärme-Instituts die Luft mit dem Brenngas verdrängt. Dabei werden bestimmte, zeitlich systematisch geänderte Strömungsverhältnisse eingehalten, so daß die Behälter mit geringem Füllgasaufwand möglichst rasch und unter Bildung einer möglichst kleinen zündfähigen Schicht in Betrieb genommen werden. Die bereits mehrfach praktisch angewandte Methode ist durch Modellversuche in einer Acrylglas-Kugel erhärtet worden.

    Notes: Eine Schicht poröser Körner werde von einem Gas oder Gasgemisch durchströmt, das sich an dem Feststoff katalytisch in exothermer Reaktion umsetzt oder aber mit der Substanz der Körner selbst exotherm reagiert (z. B. Verbrennung von Koks). Bei adiabatischer Arbeitsweise nimmt die Temperatur mit steigendem Umsatz längs der Schicht entsprechend der Wärmebilanz stetig zu. Infolgedessen steigt auch die Geschwindigkeitskonstante der chemischen Reaktion längs der Schicht an, und es können daher bei stark exothermen Umsetzungen, die auch bei höheren Temperaturen noch einseitig verlaufen, die Transportvorgänge von Stoff und Wärme zwischen Gasstrom und Feststoffoberfläche maßgebenden Einfluß auf die Umsatzgeschwindigkeit gewinnen. In einem solchen Falle überhitzt sich die Körnerschicht gegenüber dem Gasstrom, und es bildet sich unter Umständen in der Schicht eine Temperaturstufe aus, die dem Gasstrom entgegen an den Schichtanfang zurückwandert (Zündvorgang). Ausschlaggebend für diese Erscheinungen ist die Bilanz zwischen Wärmeerzeugung und Wärmeabfuhr an der Feststoffoberfläche; eine wichtige Rolle spielen hierbei die Reaktionsfähigkeit des Feststoffes (Porosität und innere Oberfläche) und der Wärmetransport in Längsrichtung der Schicht. Die Bedeutung und Auswirkung dieser Einflüsse werden im einzelnen aufgezeigt.

    Notes: In der Verfahrenstechnik der kontinuierlichen Prozeßführung mit Suspensionen kann man zwei elementare Prozeßtypen unterscheiden. Der „Entmischungstyp“ ist durch lineare Kraftfelder, in denen Partikeln „sedimentieren“, gekennzeichnet. Seine charakteristische Maßgröße ist die „Flächenbelastung“, welche bei Anwendung des „Sedimentationsgleichgewichtes“ zur Berechnung des Trenneffektes dienen kann. Der „Reaktionstyp“ ist raumfüllend und wird durch die „mittlere Aufenthaltszeit“ als Maßgröße charakterisiert. Viele Prozesse der Praxis sind Überlagerungen beider Typen. Es wird eine Prozeß-Analyse zur Ermittlung von Berechnungsgrundlagen vorgeschlagen und die räumlich oder zeitlich getrennte Durchführung der Teilprozesse empfohlen. Dadurch läßt sich der Gesamtvorgang besser anpassen.

    Notes: Zur Messung mittlerer Temperaturen mit Thermoelementen können drei Verfahren angewandt werden. Das genaueste Verfahren, die numerische Mittelbildung, ist zeitraubend; die einfachen Verfahren der elektrischen Mittelbildung erzeugen einen zusätzlichen Meßfehler. Die Auswahl des Meßverfahrens wird daher von den Anforderungen abhängen, die im Einzelfall zu stellen sind. Zur Erleichterung dieser Auswahl werden die drei Verfahren im folgenden einander gegenübergestellt; ihre Vor- und Nachteile werden angegeben und die zu erwartenden Meßfehler abgeschätzt.

    Notes: Die Graphit-Anoden werden bei der technischen Chlorat-Herstellung vor allem durch Oxydation, weniger durch Schlammbildung abgenutzt. Es wurde die Lebensdauer verschiedener Graphit-Anoden durch Versuche im Betrieb und durch Laboratoriumsversuche unter betßriebsähnlichen Bedingungen ermittelt. Hierzu wurden die durch Oxydation entstehende CO2-Menge sowie die Anodenschlamm-Menge bestimmt.

    Notes: Die besonderen Werkstoffanforderungen des Hochdruckbaues nahmen ihren Anfang vor knapp einem halben Jahrhundert mit dem Beginn der Ammoniak-Synthese. Mit dem Aufzeichnen der Entwicklung in dieser Zeitspanne an markanten Beispielen wird gleichzeitig der jetzige Stand der Technik veranschaulicht. Behandelt werden insbesondere die Festigkeitsstähle des chemischen Hochdruckbaues, die druckwasserstoff-beständigen niedrig- und hochlegierten Stähle sowie die Anwendung dieser Stähle unter den Einwirkungsbedingungen verschiedener chemischer Verfahren.

    Direkte Berechnung der theoretischen Bodenzahl bei Destillation idealer Zweistoffgemische mit unterschiedlichen Verdampfungswärmen und bei endlichem Rücklaufverhältnis (1957)

    Notes: Die Bodenzahl einer Kolonne wird oft graphisch ermittelt. Vereinfachend werden meist die molaren Verdampfungswärmen für alle Komponenten gleich groß angenommen. Will man die Unterschiede in den Verdampfungswärmen, die bei scharfen Bedingungen einen erheblichen Einfluß auf die Bodenzahl haben können, berücksichtigen, so wird das zeichnerische Verfahren sehr kompliziert. Es wurde deshalb versucht, die Bodenzahl unmittelbar zu berechnen. Der Grundgedanke der Berechnung der Mindestbodenzahl (bei einem Rücklaufverhältnis v = ∞) führt auf elementarem Weg zu einer Lösung mit drei geometrisch anschaulichen Größen.
