Abstract: The approximate analytical spline method is used to perform a prediction study into the efficiency of ribbed heat absorbers cooled by a forced flow of a chemically reacting gas delivered into interrib channels. The general case is treated, where a catalytic reaction occurs on the rib surface, which proceeds at finite rates in the diffusion-kinetic and kinetic modes. Prediction data are obtained using dissociating ammonia and methane-steam mixtures as an example.
