Abstract Two self-similar problems about plane nonstationary gas scattering in a vacuum behind a deflagration wave for which the conservation laws are satisfied are considered. The energy flux density is considered to vary according to a power law. In the first problem the gas is transparent and scattered adiabatically. The solution is found analytically. It is shown that the Jouguet condition is conserved for a flux growing with time, while such a condition is not satisfied for a decreasing flux, and the parameters on the wave depend on the flow behind it. In the second problem, the gas absorbs radiation, where the absorption coefficient varies from infinitely large to infinitely small at some transparency temperature. The motion is isothermal. A definite fraction of the incident energy, corresponding to the effective optical thickness ∼0.25, is extracted in the gas.
