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.

Book Description
Plots of property data of 380 gases and of 84 elements and compounds considered as gases display correlations which allow convenient estimation of missing data. Constants needed for the estimation of properties of gas mixtures correlate in the same fashion. It appears to be possible to rapidly estimate specific heat, viscosity, and thermal conductivity of gases and constants needed for the prediciton of mixture properties if only the empirical chemical formulas of the gases are known. The method allows a broad survey over the entire field of available gases. (Author).

Book Description
The First International Cryogenic Materials Conference (ICMC) provided a new forum for the presentation of low-temperature materials research. The confer ence, held in conjunction with the 1975 Cryogenic Engineering Conference, provided materials research personnel with excellent exposure to current develop ments in the cryogenics field and beneficial interactions with designers of cryogenic systems. Because of the large response to a late call for papers, the enthusiasm and encouragement at the meeting, and the wide spectrum and high quality of papers, the Second International Cryogenic Materials Conference is being planned along with the 1977 Cryogenic Engineering Conference for Boulder, Colorado, in the summer of 1977. The success of the First International Cryogenic Materials Conference was certainly in large measure due to the excellent hospitality of our Canadian hosts, the Royal Military College of Canada and Queen's University in Kingston, Ontario. In particular, the efforts of A. C. Leonard and his staff ensured an excellent conference and a pleasant and memorable visit to Canada. The Cryogenic Engineering Conference Board was both generous and skillful in helping to initiate this new conference and their guidance and acceptance is gratefully acknowledged. The Cryogenic Engineering Conference program chairman, M. J. Hiza, greatly facilitated the interaction for the two conferences and provided valuable assistance in generat ing a workable program. The proceedings of the 1975 Cryogenic Engineering Conference are published as Volume 21 of the Advances in Cryogenic Engineering and include many papers indicating innovative use of new cryogenic materials properties data.
