Transport properties of real gases
Abstract
Theoretical as well as semi-empirical approaches were used by a number of investigators for the interpretation, correlation, and prediction of transport properties of pure gases and gaseous mixtures. Using a theoretical approach, the Kihara potential was applied to describe the behavior of nonpolar systems. Numerical calculations of the collision integrals in terms of the Kihara potential were carried out. Satisfactory results were obtained in the prediction of viscosities and binary diffusivities of gaseous systems at low pressures. For polar systems at low pressures, the preaveraged potential model developed by Rowlinson and by Danon and Amdur was used to correlate viscosity and binary diffusivity data. Satisfactory results were also obtained. For polar systems at high pressures, the chemical association theory was extended to account for the anomalous pressure dependence of the viscosity. Experimentally, binary diffusivities of nitrogen-methane and nitrogen-methyl chloride were determined between 25 and 110 C using a modified Stefan diffusion cell.
