| Abstract: | The singularities of two-dimensional interchannel flows of a condensing and damp vapor with nonequilibrium phase transitions which contain gas-dynamic discontinuities are investigated. A through-computation difference method is constructed for such flows. The results of the numerical investigation of steam flows with spontaneous condensation in supersonic plane nozzles containing a break in the walls and flow around a wedge are represented. It is shown that nonequilibrium condensation can result in a qualitative rearrangement of the wave structure of the flow which is impossible to obtain within the framework of the one-dimensional approach.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 4, pp. 87–93, July–August, 1978. |
