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 is performed in the laminar “frozen” boundary layer with zero and absolute catalytic surface activity. In order to improve the accuracy of the calculation of heat fluxes on the catalytically active surface, a modification of the Gullard ratio is carried out. Using the modified Gullard ratio obtained in this work, calculations of heat transfer on a catalytically active surface are carried out. It is shown that the levels of heat fluxes calculated using a modified ratio of up to 30% below the levels of heat fluxes obtained from the Gullard ratio under otherwise equal conditions.
