| Abstract: | The problem of strong evaporation of matter filling periodic rectangular semi-infinite channels in a porous two-dimensional body is solved by a method of direct statistical modeling. The depths of the channels, the outer surface elements of the body, and the distance from the outer to the evaporation surface are assumed equal in order of magnitude to the mean free path of the molecules. Boundary conditions are obtained for the gas dynamics equations in Euler form, making it possible to describe adequately the flow outside the Knudsen layer. The flow structure in this last is investigated as a function of the determining parameters.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 2, pp. 130–134, March–April, 1986.In conclusion I express my gratitude to V.
