Abstract : A fundamental theoretical study of homogeneous vectored injection and suction in high speed flows with heat transfer and self-induced gradients is described, based on local similarity solutions of the laminar boundary layer equations. The results show the important effects of both injection velocity and vector angle on a variety of physical properties of practical interest such as velocity and temperature profiles, skin friction, heat transfer rate, displacement thickness and induced pressure field. In addition, the existence of a new set of solutions pertaining to upstream-vectored injection is established and investigated. Moreover, it is shown that the frictional heating associated with the tangential injection velocity component can significantly influence the heat transfer characteristics of high speed flows.
