Аннотация

A physical model is developed for math modeling of interphase interactions at the hot gas–water interface. The heat-and-mass transfer processes in two-phase flows appear at interfaces of phases. Profiles of the heat-and-mass transfer rates versus properties of phases and mode parameters are presented based on the Nusselt criterion equations. The hydrodynamic problem is solved numerically by integrating a set of equations of continuity, Navier–Stokes and energy equations using a control volume method (CVM). The conservation equations are supplemented with source terms: an equation of continuity—with a mass evaporation rate, an energy equation—with heat of interphase interactions. The computation results are compared with experimental data.
