Available in PDF, EPUB and Kindle. Book excerpt: A computer program has been developed to solve the boundary layer equations for laminar flow over a heated plate with H2/air combustion. The objectives are to investigate the importance of homogeneous as opposed to catalytic surface reactions during the combustion process, and to determine the roles of heat and mass transfer and their effect on combustion. Results are presented for combustion of H2/air at an equivalence ratio of 0.1 for flow over a noncatalytic plate at a surface temperature of 1100°K. A detailed mechanism involving 8 chemical species and 13 reactions has been used to describe the kinetics. The reactions leading to the initiation of combustion and the effect of the large diffusivity of hydrogen are discussed. The boundary conditions for catalytic surface and a simplified model to account for catalytic wall reaction are formulated. Results are presented for combustion over a catalytic surface and compared with the non-catalytic case.
