The mathematical modeling of mixed convection of a viscous incompressible fluid in a rectangular area with a local heat sink and sources of input and output of mass are carried out. Solved the system of non-stationary Navier-Stokes equations in the dimensionless formulation. Was examined the mode of mixed convection of a viscous incompressible fluid at Re = 1000, Gr = 106, Pr = 7.1. Analyzed the contours of stream function and temperature field in this area. Studied the Influence of the heat sink and its location in the water on the formation of convective flows and changes in temperature regime. Investigated the basic regularities heat transfer in the study area . Established that the distribution of heat flux occurs mainly in the horizontal direction of main flow. Analyzed the influence of the location of the heat sink and the Reynolds number on the intensity of heat exchange.
