- 中文摘要: Viscosities of noble gases have been calculated over a wide temperature-pressure range. Simple and accurate Tang-Toennies potential of the noble gases are used in the Chapman-Enskog calculation of the zero density viscosity and in the Rainwater-Friend theory to determine the initial density dependence of the viscosity. At densities beyond the range of the theory (up to 46 mol.dm-3), a variant of the residual viscosity is developed. A correlation function for the calculation of viscosity over the whole range of density is presented. A comparison of the calculated and experimental values of the viscosity yields an average absolute deviation of 1.5%.
