Light-induced heat and mass transfer of gas in a plane channel

The paper deals with the processes of heat and mass transfer of a rarefied gas in a plane channel in the field of resonance radiation. The problem is solved using linearized kinetic equations with a first-order model integral of collisions. The surface and collision mechanisms of light-induced drift are investigated, as well as the mechanism of heat flux at arbitrary values of the Knudsen number. Analytical expressions for channel cross section-averaged flows are obtained at high and low values of the Knudsen number.
