Abstract : The effect of arbitrarily distributed surface chemical activity on heat transfer has been studied and equations describing the diffusion rate of atoms to a surface in contact with a frozen boundary layer have been developed. A Volterra integral equation, is used and it can be solved either by a series method or by a numerical scheme. A detailed development was presented for surface catalytic recombination of atomic species of a disociated diatomic gas flowing over a flat plate. Two basic cases were included: the surface on the front portion as (1) a perfect catalyst or (2) a total noncatalyst. In the examples presented only the non-catalyst case is shown, since this was the only case for which all the methods of solution developed could be readily compared. (Author)
