The current of a vertical jet with other temperature in rectangular area is considered. For simulation of the given process Navier-Stokes equations for turbulent currents in approximation by Reynolds, equation of heat transfer, equation of continuity are used. The equations are decided in natural variables . We assume, that above on each side is having overflow. On a part of the boundary of area, where the solid walls are assumed, as boundary conditions the conditions of an adhesion are accepted for a velocity, and the condition of tightness is accepted for temperature. On a site of the boundary, where liquid flows to considered area, both components of a velocity and temperature are given. The distribution of temperature on rated area is investigated. The field of temperature, field of rates is found. The fundamental vortical movements originating in result diverse density currents are defined. Some laws of infringement of stratification stability as a result of vertical stirring action are established.
