Abstract

A numerical study is made of mixed flow of a gas-dispersion and a vapordroplet mixture in a nonaxisymmetric nozzle (with two planes of symmetry) and an immersed supersonic jet. Allowance is made for the possibility of evaporation and condensation growth of droplets, and for the effect of difference between the temperatures of finely divided particles and gas on their momentum and energy transfer. It is shown that the nonaxisymmetric nature of the nozzle leads, for example, to very inhomogeneous azimuthal distributions of the number density and sizes of the particles. These effects may be used in order to control the influence of the two-phase jet on the surface and in order to change its emission indicatrix in three dimensions.
