Abstract : Utilizing recent hypersonic flow experiments as a data base, several features of turbulent boundary layer characteristics were examined in order to provide improved engineering design capability, accounting for the effects of angle of attack, Reynolds number, compressibility, mass transfer and injectant molecular weight. These features consisted of the Crocco temperature-velocity relationship, the boundary layer profile shape and viscous layer thickness relations, and heat blockage and skin-friction reduction due to mass injection.
