AbstractA theoretical model is suggested to describe intensified heat exchange for turbulent flows within channels equipped with turbulence promoter. The model is based on balance equation for turbulent pulsating energy derived for open surface valleys withrelatively small turbulence promoters. Heights of the promoters are comparable in this case with a thickness of a buffer area. Numerical simulation data are obtained for these conditions. These data correspond satisfactorily to existent experimental data.
