Rapid evaporation and condensation of gas between two surfaces in the limit of low values of Knudsen number
Annotation
One-dimensional plane, cylindrical, and spherical flows are considered, which arise in the case of rapid evaporation and condensation of gas. It is demonstrated that the main similarity parameter is $\overline{p}_{\text{ev}}$, i.e., the ratio of saturated vapor pressures at temperatures of “hot” and “cold” surfaces. The boundaries of the regions of limiting steady-state flows are investigated. The existence is demonstrated of the optimal value of the ratio of surface radii, at which the flow assumes the limiting mode at minimal value of $\overline{p}_{\text{ev}}$. The effect of polyatomicity of gas is considered.
