Abstract:

There is treated a laminar flow which is simple from the fluid mechanical and chemical points of view but which involves multi-component diffusion and relatively accurate transport properties. Thus a similar boundary layer with hydrogen injection and with chemical behavior idealized according to the flame sheet model is considered. On the basis of several numerical examples it is found that there is predicted by the present analysis boundary layer behavior significantly different from that given by analyses with simple transport e.g., the velocity profiles with hydrogen injection resemble suction profiles because of the reduction in the rho mu product. Accordingly, the accuracy of existing analyses involving species with a spectrum of molecular weights and employing the assumption of simple transport properties would appear doubtful. Author
