Calculation of heat transfer on the catalytically active surface of high-speed aircraft

The scientific paper analyzes the influence of the catalytically active surface on the intensity of heat and mass transfer in a chemically active boundary layer. Some features of the mechanism of heat and mass transfer under conditions of heterogeneous catalysis are indicated. Heat transfer analysis...
