Abstract:
A method to analyze the influence of chemical reactions on heat-and-mass transfer in a reactive boundary layer has been suggested, and the influence of thermal effects on the overall heat-and-mass transfer coefficient has been estimated. It has been found that endothermal reactions in the boundary layer have a considerable effect on the overall heat-and-mass transfer coefficient. Taking into account the influence of thermal effects due to homogeneous reactions inside the boundary layer on convective thermal flux $\dot{q}_{\lambda}$ is equivalent to taking into account the heat of these reactions on the surface of a heat protection coating, that is, on the surface of a coked layer.
