- Аннотация: The unsteady two-dimensional problem of the reflection of a uniform supersonic rarefiedgas flow incident normal on a wall with an orifice and the gas outflow through the orifice (slot or channel) is solved on the basis of the kinetic S-model. The slot influence on the reflection nature, thevelocity of the shock wave reflected from the wall, and the formation of a gas jet flowing out into a vacuum is studied as a function of the incident flow velocity, the gas rarefaction degree, and the conditions imposed on the wall. The effect of the wall thickness, that is, the length of the channel, throughwhich the gas flows out, is also investigated. The gas flow rate through the orifice is calculated as themain integral characteristic. The attainment of steady reflection regime in the outflow process istraced. The kinetic equation is solved numer
