Tkachuk is offered. It based on geometrical analysis of idealized macrostructure shown as a growing or constant radius vortex sheet. The small vortices in flows with a large-scale macrostructure plays secondary roles because they have incommensurably less energy than big vortices. They can be eliminated from consideration. We specify the velocity and temperature profile that differs from the jet boundary layer profile and better coincides with experiment. We find a growth law for a free boundary layer and length of currents cores. This approach help us to solve the actual task for energy efficient heating systems. We found the heat exchange coefficient between flows. It allows simulating the back flow effect in onepipe radiator nodes. The results of calculations coincides with well-known literature data. popup.nrat_date 2026-04-20 Close
