Abstract: The criteria of similarity describing interphase heat exchange in a two-phase jet are received. By means of the given mathematical model of a two-phase jet calculations which have allowed to connect sizes of the received criteria of similarity with the maximum relative difference of phases temperatures in a jet are carried out. Results of work give the chance on size of phases parameters on a cut of a nozzle to define, what complexity in this concrete case there should be a mathematical model of a two-phase jet — whether it is necessary to write down the equation of particles energy or at calculations it is possible to accept temperature of particles to equal temperature of gas, having excluded from the equation of gas energy the member describing interphase heat exchange.

Keywords: two-phase jet, mathematical model, heat exchange between phases, criteria of similarity.
