A nonequilibrium system consisting of a gas, a surface, and a solid body in problems of relaxational gas dynamics

An analysis is presented of a model of a flow of a multitemperature disperse medium as a possible reservoir and carrier of energy which can be converted into radiation. It is assumed that an external source, e.g., an electron beam, can excite intramolecular oscillations in aerosol particles (e.g., of nitrogen), whose energy is transferred to the gas phase by the resonance exchange of quanta on the particle surface. Attention is given to the combined problem of gas dynamics and kinetics with allowance for vibrational relaxation inside the particle, on the surface, and in the gas phase.
