Abstract:

The viscous supersonic flow past a flat plate-compression ramp is considered in the limit of infinite Reynolds number. The limit-flow structure is given by the Stewartson-Neiland triple-deck theory. A numerical scheme for solving the limit-flow problem is discussed, together with numerical aspects of the solution. The accuracy of the limit solutions, when applied at finite Reynolds number, are tested for accuracy by a systematic comparison with results of the Werle-Vatsa interacting boundary-layer model. The paper is concluded by discussing the more complex flow structure resulting when the ramp angle is too large to be consistent with triple-deck theory.
