Abstract

A numerical simulation of the separation of a two-component gas mixture with similar molecular masses in a heat micropump based on the radiometric effect is carried out. The simulation method is based on the direct solution of the Boltzmann kinetic equation using a splitting scheme. Relaxation problems are solved using the conservative projection method. The transport equations are solved using first- and second-order schemes. Design of a facility is proposed that can be used to separate mixtures of gases with similar molecular masses. The simulation is used to evaluate the efficiency of this facility.
