On the utility of the m-6-8 potential function
H. J. M. Hanley · 1972
The calculation of transport and equilibrium properties of simple gases with the m-6-8 potential function is discussed.Properties referred to specifically are the viscosity, diffusion, thermal conductivity and second virial coefficients, and the thermal diffusion factor , Gases referred to are argon, krypton, xenon, nitrogen, oxygen, carbon dioxide and methane.We also discuss in detail the genera] behavior of a model potential with respect to the fitting of data and the selection of potential parameters.The m-6-8 appears to be the simplest model potential which can satisfactorily be used to fit data over a wide temperature range.The relationship of the potential to independent theory is briefly examined.
