Light-induced heat flux and drift of one-component gas in a flat channel

Processes of heat transfer and drift of rarefied gas in a flat channel due to the resonance absorption of the optical radiation of atom selectively on their velocities have been studied. The flux profiles and kinetic coefficients determining the surface and collision mechanisms of light-induced phenomena of transfer in the one-component gas in a flat channel have been calculated on the basis of the numerical solution of the kinetic equations depending on the values of the Knudsen number and the ratio of the frequency of the radiation decay of the excited level of atoms to the frequency of the molecular collisions.
