The effect of condensation coefficient on the parameters of flow in problems on strong re-condensation

One-dimensional plane, cylindrical, and spherical flows are considered, which arise in the case of strong re-condensation of gas in the limit of small values of Knudsen number. The effect of the value of condensation coefficient α on the flow is considered. The effect of α on the boundaries of the regions of subsonic, mixed, and supersonic flows is investigated. It is demonstrated that the decrease in the ratio of “hot”-to-“cold” surface radii causes a significant decrease in the effect of the difference of α from unity on the pattern of recondensation flow. The effect of polyatomicity of gas is considered.
