はく離せん断層の現象解明と制御戦略の変遷と展開

抄録

The article describes a review of the researches on the separating shear layer over the backward-facing step and its control since 1960. The separating shear layer over the step is one of the typical flows which involves the vortex evolution and reattachment process after the boundary layer separate at the step. There are many papers on the flow control techniques and devices in the backward-facing step flow, since it is easy to evaluate the effect of flow control method quantitatively by comparing the reattachment length under the different control conditions. The recent trend on the flow control is also discussed.
