The formulation and description of a quasihomogeneous mathematical model of gas-dispersed flows in the presence of a nonequilibrium gas-phase and heterogeneous chemical reactions is given. The case where, in addition to fine particles, relatively large particles of a dispersed phase are present in a quasihomogeneous gas-dispersed mixture is considered.

Keywords: gas-dispersed flows, heat and mass transfer processes. phase transitions, heterogeneous chemical reactions, thermogasdynamic
