    The influence of surface coverage on catalytic effectiveness and selectivity. The isothermal and nonisothermal cases (1966)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 12 (1966), S. 20-23 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Notes: Both nonisothermal and isothermal catalytic effectiveness factors are computed for kinetic rate laws of the Langmuir-Hinshelwood, Hougen-Watson type, involving surface coverage by reactant and products. Selectivity taxation is also treated and the significant influence of interphas heat and mass gradients surrounding the catalyst is displayed. The complexities of these real kinetic systems suggest caution in the use of prior generalizations based upon simpler rate laws.

    The condensing of low pressure steam on vertical rows of horizontal copper and titanium tubes (1966)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 12 (1966), S. 31-35 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Heat transfer data are presented for condensing steam at 2 in. Hg absolute pressure on the outside of nine copper and nine titanium horizontal tubes in a vertical row. The condensing coefficient correction factor was maximum for the top titanium tube and was 46% higher than the correction factor for the top copper tube. The difference between the correction factors for titanium and copper tubes diminished with the number of tubes in a vertical row to 8% higher than the correction factor for copper tubes with six to nine tubes in a vertical row.

    Pressure drops and void fractions in horizontal two-phase flows of potassium (1966)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 12 (1966), S. 50-58 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Vapor-liquid flow of a potassium-8% sodium mixture was studied with the use of a boiling heat transfer test loop. Pressure drop data were obtained from a 36-in. long, 0.495-in. I.D. unheated test section. Void fractions were measured at the midpoint of the test section with gamma ray attenuation.Flows were essentially frictional. Quality, total flow rate, and absolute pressure were the principal variables affecting the pressure drop results, which were correlated in terms of a two-phase friction factor. A metallic void fraction correlation was developed from previously reported data for other metallic fluids together with the potassium data of this study.The potassium two phase friction factors fall substantially lower than values predicted by well-known frictional pressure drop correlations. Metallic void friction values are appreciably lower than data for other fluid systems. Velocity slip ratios appear to be much higher than for other fluid systems due to high liquid-to-vapor density ratios and low void fractions.

    Heat transfer to non-Newtonian fluids in transitional and turbulent flow (1966)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Turbulent and transitional flow heat transfer correlations for non-Newtonian fluids are presented. By means of an extension of the Reichardt-Metzner-Friend correlation to nonisothermal flow, and a new definition of Prandtl number to account for deviations from Newtonian behavior, turbulent flow data are correlated to a standard deviation of 14.8%. By means of a normalizing procedure, data for the complex case of transitional flow heat transfer to non-Newtonian fluids are correlated to a standard deviation of 17.7%. At the transition region boundaries, the correlation is consistent with laminar and turbulent flow correlations. A basic similarity in the Newtonian and non-Newtonian heat transfer mechanisms is suggested.

    Momentum, heat, and mass transfer in turbulent non-Newtonian boundary layers (1966)

    Notes: The boundary-layer equations and a Blasius type of relationship between f and NRe gen are used to derive expressions for velocity distribution, local boundary-layer thickness, local shear stress, and total drag force for the turbulent boundary-layer flow of a power law non-Newtonian fluid across a flat plate at zero incidence. Relationships are derived for the velocity at the edge of the laminar sublayer and for the thickness of the laminar sublayer.An analogy between heat and momentum transfer is then used to obtain expressions for local and mean values of the heat transfer coefficient in a turbulent thermal boundary layer for power law materials flowing over flat plates. Analogous extensions to mass transfer are indicated.A tentative criterion is suggested for characterizing the transition from laminar to turbulent boundary-layer flow of power law fluids.Relationships combining the effects of a part laminar, part turbulent boundary layer are presented.

    Effect of ultrasonic waves on mass transfer rates of selected fluids (1966)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 12 (1966), S. 90-95 
    Details
    ISSN: 0001-1541

    Notes: The application of ultrasonic energy to a fluid in a capillary has resulted in greatly increased rates of mass transfer (of the order of 800 to 2,000% above that without insonation) to occur at specific heights in the capillary. Reproducible results with several selected fluids (carbon tetrachloride, acetone, ethanol, and methanol) have shown that these specific heights are always at the half wavelengths of the particular fluid investigated. The mathematical model developed herein predicts that at these half wavelengths, the fluid particle displacement of the ultrasonic wave becomes quite large, exceeds the threshold value necessary for the stability of the surface waves, and causes droplets to be ejected into the vapor above the surface in the form of a fog. The resulting decrease in the diffusional path length of the ejected fluid provides the final mechanism for an increased mass transfer from the capillary tube.

    A generalized equation for computer calculation of liquid densities (1966)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 12 (1966), S. 95-99

    ISSN: 0001-1541

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A generalized equation explicitly relating reduced density to reduced temperature and reduced pressure has been developed for calculating liquid densities of pure compounds on a digital computer. The analytical formulation is based mainly on a modified corresponding states principle and the graphical correlation of Lydersen, Greenkorn, and Hougen. The calculated densities from the equation reproduce the literature data within 2% for sixty-two saturated liquids and nineteen compressed liquids.With the aid of a pseudocritical method and a generalized equation of vapor pressure, the same equation is readily applied to the estimation of liquid mixture densities. The method of Prausnitz and Gunn is chosen for the evaluation of pseudocritical constants. For fifteen binary systems, one ternary system, and one quinary system, the one hundred fifty-nine calculated densities agree with the literature data to within 3%. This method is limited to pseudoreduced temperatures less than 1.0.
