Separation of Multicomponent Isotope Mixtures by Gas Centrifuge

A phenomenological and kinetic description of diffusion and heat transport in multicomponent gas mixtures and plasma

“…43,44 Another example is related to the analysis of the effect of the separation of multicomponent (isotope) gas mixtures in high-speed gas centrifuges, where the use of the diffusion equations in the Stefan-Maxwell form also demonstrates its effectiveness. 48,49 We can also cite another series of cases where the description of diffusion and heat transport in gases and plasma on the basis of the "forces in terms of fluxes" representation is the most optimum. The advantages of this approach for analysing diffusion and heat transport of heavy impurities in the hydrogen plasma of experimental devices for the magnetic containment of plasma, for example, have been considered in detail, as well as the separation of many varieties of ions in a rotating plasma.…”
