The three-dimensional mixing field induced by a novel wall-mounted cavity having a three-dimensional shape, which has been proposed in the other literature, is investigated in detail by solving the Reynolds-averaged Navier-Stokes (RANS) equations computationally. The results indicate that secondary flows are produced from the cavity and that the secondary flows act on the transverse jet such a way that it penetrates highly into the primary flow; i.e., the computational results demonstrates that the proposed cavity functions effectively as a device for enhancing supersonic mixing.
