The paper presents the results of experimental studies obtained in a special test stand, which was carried out with the addition of mass flow, summarizes the theoretical analysis of the phenomena occurring in the flow, and the calculations, which were performed using the modeling of flow in the channel. The two examples of model calculations for the two laminar Reynolds number values are shown. Paper presents: channel scheme for analyzing the flow arising as a result of adding mass, two-dimensional diagram of the computational domain with the mass addition, grid computing domain, two-component velocity field, the lines of current in the channel, the distribution of the vector field in the channel, the average velocity as a function of the distances, the speed and temperature distributions for each channel cross-sections for flow with various values of the Reynolds number. The increase in lateral velocity Vb , while maintaining constant lower speed Vd , decreases the thickness of the boundary layer, both the velocity and the thermal one, which was also referenced in experimental investigations, carried out on the special test rig, using LDV and PDPA laser techniques.
