Book Description
Summary: In problems involving fluid flow, heat transfer, and mass transfer of gases, the viscosities, thermal conductivities, and diffusion coefficients are required. Direct measurements are in any event time consuming--they may be impossible. Alignment charts (nomographs) for calculating the low-pressure transport properties of nonpolar gases and gas mixtures are presented. Calculations for pure gases are based on the rigorous kinetic theory of gases as applied to a realistic intermolecular force law. Mixture viscosities and conductivities are calculated from good approximations derived from rigorous theory. Properties can be calculated quickly with a precision of 2 percent or better. Accuracy depends on how well the constants characterizing the intermolecular force law are known; if constants are derived from experimental data, results should be accurate to 5 percent or better. Force constants for 65 gases are tabulated.

Book Description
A method for calculating viscosity and thermal conductivity of a helium-xenon (He-Xe) gas mixture was employed, and results were compared to AiResearch (part of Honeywell) analytical data. The method of choice was that presented by Hirschfelder with Singh's third-order correction factor applied to thermal conductivity. Values for viscosity and thermal conductivity were calculated over a temperature range of 400 to 1200 K for He-Xe gas mixture molecular weights of 20.183, 39.94, and 83.8 kg/kmol. First-order values for both transport properties were in good agreement with AiResearch analytical data. Third-order-corrected thermal conductivity values were all greater than AiResearch data, but were considered to be a better approximation of thermal conductivity because higher-order effects of mass and temperature were taken into consideration. Viscosity, conductivity, and Prandtl number were then compared to experimental data presented by Taylor. Johnson, Paul K. Glenn Research Center NASA/CR-2006-214394, E-15672
