Displacement-thickness induced pressures on a flat plate with homogeneous and heterogeneous vectored injection
Abstract
The effect of vectored heterogeneous injection in a flow field with pressure gradient is examined. A first-order approximation is presented for the problem of strong-interaction flows which may not be treated under the category of similar solutions. The results show that displacement thickness and induced pressures decrease with increasing angles of injection, whereas skin friction and wall heat transfer increase as compared to the normal injection case. These results, which represent a first-order effect of surface mass transfer on induced pressures, may be utilized to recompute the flow field for an interaction problem.
