    Effect of a cylindrical boundary on a fixed rigid sphere in a moving viscous fluid (1960)
    Hoboken, NJ : Wiley-Blackwell

    Notes: In this investigation of the effect of a cylindrical boundary on a spherical particle suspended in a moving viscous fluid the pressure drop due to the motion of fluid past a stationary sphere and the drag on the sphere are independently measured, and the sphere- to-cylinder-diameter ratios varying from 0.1250 to 0.3125 are studied at different positions of eccentricity. The investigation shows that in the range of Reynolds numbers from 0.1 to 40.0, based on the approach velocity to the sphere and the diameter of the sphere, the pressure drop due to the presence of a sphere and the drag on it can be represented by a semiempirical relationship containing two terms. One term, owing to the effect of the cylindrical boundary, is derived theoretically from the creeping-motion equations which neglect inertial effects. The second term, owing to the inertial effects, is established from data on the drag coefficient of a sphere in on unbounded medium.

    On the separation of gas mixtures in a jet (1960)
    Hoboken, NJ : Wiley-Blackwell

    Notes: In 1954 Becker found that the components of a gas mixture could be separated by allowing a jet of the gas mixture to expand in a low-pressure chamber. The heavier molecules would concentrate near the center of the jet and the lighter ones near the edge. Thus the jet could be split into two streams, one containing more of the heavy component and one containing more of the light component. In this paper it will be shown that this effect can be predicted from the kinetic theory of gases and that the predicted magnitude of the effect agrees favorably with the experimental data of Becker.

    Notes: Pressure-volume-temperature measurements have been made on methyl borate over the temperature range of 2257deg; to 300°C. and pressures of 30 to 200 atm. in a variable volume P-V-T bomb. Vapor-pressure measurements from 180°C. to the critical point have also been made with the same apparatus. The vapor-pressure data are presented in the form of the Antoine equation, and the P-V-T data together with the vapor-pressure data have been fitted to the Benedict-Webb-Rubin equation of state.

    Mass transfer in liquid-lithium systems (1960)

    Notes: The behavior of type-304 stainless steel in a forced-convection closed-loop lithium system was investigated over a wide range of temperatures and velocities. Fundamental information concerning the mechanism for mass transport has been obtained by examining solution and deposition effects along flat plates. The rate-determining process for solution is transport from the solid to the interface, whereas deposition rates are liquid-phase controlled.Liquid-phase mass transfer coefficients were correlated with a maximum deviation of approximately 15% by the use of von Kàrmàn's analysis of the turbulent boundary layer along a flat plate, combined with the Chilton-Colburn empirical modification of the Schmidt group. In contrast no adequate model is available for the prediction of solution rate constants which must be determined experimentally. Mean values of the solution rate constants ranged from 0.154 to 0.750 × 10-5 cm./sec. at temperatures from 510° to 612°C. These values are on the order of 103 smaller than corresponding liquid-phase mass transfer coefficients.

    The motion of two spheres following each other in a viscous fluid (1960)
    Hoboken, NJ : Wiley-Blackwell

    Notes: The purpose of this investigation was to determine the interaction effect of one spherical particle upon another when both are falling in a viscous fluid. The velocities of two identical spheres, falling along the axis of a cylinder in a direction parallel to their line of centers, were measured experimentally as a function of the center-to-center distance between them at very low Reynolds numbers. The experimental results compared very well with theoretical studies found in the literature which predicted that two spheres will fall faster than one sphere.At Reynolds numbers greater than 0.25 the influence of inertial effects were studied for one end two spheres. The experimental results qualitatively confirmed the Oseen equations. A definite attraction between two spheres falling one above the other was observed; the inertial forces acted to slow down the lower sphere without affecting the upper one.

    Notes: New measurements of the volumes of liquid n-alkanes of 7, 9, 11, 13, 17, 20, 30, and 40 carbon atoms over a range of temperatures from 20° to 300°C. and pressures from 0 to 4,000 kg./sq. cm. have been made. These volume measurements are here reduced to compressions (volpT)/(vol°T), and the accuracy of the measurements has been determined. Analysis of the data for n-heptane and n-eicosane shows that the order of accuracy of the compressions of each of these compounds appears to be approximately 3 parts in 10,000. Evaluation of random multiple measurements on the remaining six compounds indicates that their over-all accuracy is likewise of this same order.
