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.

Collection of Heat-transfer Properties of Gases at Moderate Pressures, and Rules for Rapid Estimation of Missing Data
Author: Franz Josef Neugebauer
Publisher:
ISBN:
Category : Gas
Languages : en
Pages : 446
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).
