Download or read book A Method for Calculating Viscosity and Thermal Conductivity of a Helium Xenon Gas Mixture written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-24 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Estimated Viscosities and Thermal Conductivities of Gases at High Temperatures written by Roger A. Svehla and published by . This book was released on 1963 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1996-01-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is addressed to specialists working in the field of power engineering and chemical technology for processing foodstuffs, as well as engineers, students, and researchers concerned with investigations of thermophysical properties of gases and liquids in the critical region. The foundations of modern theory of transport phenomena in the vicinity of the liquid-gas critical point and procedures for calculating viscosity and thermal conductivity, based on the theory, are presented. The relationship between equilibrium and nonequilibrium properties in the critical region is studied in order to develop reliable self-consistent tables of thermal properties of substances.
