- Аннотация: In the framework of the two-continuum model of a compressible gas?droplet boundary layer in a supersonic two-phase flow on a plane wall, the fields of phase parameters, droplet trajectories, and mass and energy fluxes of the dispersed phase on the streamlined surface are calculated. In the interphase momentum exchange, in addition to the aerodynamic drag force, the Saffman lift force resulting in droplet deposition on the solid wall is taken into account. The mass concentration of the dispersed phase is assumed to be small, and the wall temperature exceeds the temperature of droplet evaporation. The effect of evaporating droplets on the equilibrium temperature of a heat?insulated (adiabatic) wall is studied in a wide range of dimensionless governing parameters. It is shown that the presence of even a very low concentration of droplets can lead to a considerable decrease in the temperature of the adiabatic wall, which makes use of the evaporating condensed phase promising in different schemes of energy separation of gas flows.
