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
Progress in International Research on Thermodynamic and Transport Properties covers the proceedings of the 1962 Second Symposium by the same title, held at Purdue University and the Thermophysical Properties Research Center. This symposium brings together theoretical and experimental research works on the thermodynamic and transport properties of gases, liquids, and solids. This text is organized into nine parts encompassing 68 chapters that cover topics from thixotropy to molecular orbital calculations. The first three parts review papers on theoretical, experimental, and computational studies of the various aspects of thermodynamic properties. These parts discuss the principles of phase equilibria, throttling, volume heat capacity, steam, volumetric behavior, enthalpy, and density. The subsequent part highlights the theoretical evaluations of transport properties, such as viscosity, diffusion, and conductivity, as well as the transport processes. These topics are followed by surveys of the theories in intermolecular forces and their applications. Other parts consider the measurement of thermal conductivity, viscosity, and radiation. The final parts examine the properties of ionized gases and non-Newtonian fluids. This book will prove useful to mechanical and chemical engineers.

Book Description
Viscosities and thermal conductivities, suitable for heat-transfer calculations, were estimated for about 200 gases in the ground state from 100° to 5000° K and 1-atm pressure. Free radicals were included, but excited states and ions were not. Calculations for the transport coefficients were based upon the Lennard-Jones (12-6) potential for all gases. Intermolecular force constants for this potential were obtained from experimental viscosity data or were estimated when data were not available. The same set of constants was used to calculate both viscosity and conductivity. An Eucken-type correction for exchange between internal and translational energies was made for thermal conductivities of polyatomic gases.
