A plane mixing layer with cross-shear
The effect of cross‐shear on a nominally two‐dimensional plane mixing layer is investigated. A temporal mixing layer is generated with a stratified tilting tank similar to that used by Thorpe [J. Fluid Mech. 32, 693 (1968)], and cross‐shear is introduced to this mixing layer to simulate situations the authors believe are widespread in industrial and natural flows. A new type of ''co‐rotating'' streamwise vortices arises from the introduction of cross‐shear, and the mixing rate is found to be greatly enhanced.
