The effect of flow non-uniformity on the supersonic mixing layer was investigated. The mixing layer is formed at the interface between the parallel supersonic flows of air and helium. The mixing layer was directly investigated by measuring the concentration ratio of helium. As for the flow non-uniformity, the stream-wise pressure gradient and the shock wave penetrating the mixing layer were considered. The effect of the stream-wise pressure gradient enhances the mixing rate by around 2 times in comparison with the one of the mixing layer without the effect. The shock impingement further enhances the mixing rate in comparison with the one of the mixing layer with the stream-wise pressure gradient but without the shock impingement. The enhancement of the mixing layer growth rate caused by the flow non-uniformities is attributed to the vorticity enhancement at the mixing layer, for which the baroclinic torque is a strong candidate. |
