Mixing processes in the turbulent two-phase jet confined at some distance from the nozzle aremodeled and examined. Many natural and technical phenomena deal with the turbulent mixing and heattransfer in the jet of mutually immiscible liquids, which represent an important class of the modern multiphasesystems dynamics. The differential equations for axially symmetrical two-dimensional stationary flow and theintegral correlations in a cylindrical coordinate system are considered for the free heterogeneous jet confined atits initial or ground part in the cylindrical channel. Algorithm and the results obtained may be of interest for theresearch and industrial tasks, where the calculations of the turbulent mixing and heat transfer in multiphase jetdevices are of importance.
