Calculation of thermal-diffusion separation in a mixture of gases

A method for calculating thermal-diffusion separation in a multicomponent mixture of gases is presented that does not require the application of either a thermal-diffusion coefficient or other quantities associated with it (a thermal-diffusion ratio, a factor of thermal diffusion). A comparison of the calculated results with experimental data for binary mixtures is given. Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 70, No. 1, pp. 60–63, January–February, 1997.
