Modeling of Heat and Mass Transfer in Polydisperse Turbulent Jets with Coagulation, Break-up, and Evaporation of Droplets

ABSTRAKT

Stationary nonisothermal two-phase turbulent jets (TTJ) with coagulation, break-up, and evaporation of droplets are considered. The TTJ model is developed using the transfer equation of turbulence energy. The boundary layer theory limits are exact and it is possible to neglect rotation of droplets. The equations are solved numerically. Results of the calculations agree well with experimental data. The calculations with account for interactions between droplets lead to slowing down of the reduction of a mean diameter of roplets. As a result, interphase heat transfer decreases.
