Turbulent heat and mass transfer under interaction of various disturbing factors

Both integral and local characteristics of turbulent heat and mass transfer are treated in this paper. The structure of Reynolds stresses and turbulent heat fluxes at the immediate vicinity to the wall is studied. The effect of external turbulence on the turbulent transfer intensity in presence of injection was shown to increase substantially with increasing injection parameters. The reaction front decreases the intensity of heat and mass transfer as compared to the injection without reactions. The injection and thermal radiation enhance the boundary layer, smoothing the temperature fields and redistribute the components of heat fluxes across the layer thickness with prevailing convection at its boundaries.
