Аннотация:The structure of normal and oblique compression waves in a gas-droplet mixture with droplet evaporation, as well as the symmetric interaction (or reflection from a wall) of oblique compression waves in this medium, are investigated. The main attention is paid to little-studied problems of finding the limits of existence of waves with qualitatively different structure in the space of dimensionless governing parameters. Using the generalized Rankine-Hugoniot relations, the conditions of existence of partly and fully dispersed waves with complete and incomplete droplet evaporation are found. Numerical calculations are performed, which illustrate the distributions of phase parameters in waves of different structure. For the first time, the ranges of two-phase flow parameters and characteristics of crossing oblique compression waves with evaporating droplets are found, for which the reflected waves degenerate into fully dispersed waves or completely disappear.
