主流中に吹出すSweeping jetが作り出す三次元渦構造とその生成過程

抄録

The sweeping jet has been attracted attention as active flow control and mixing acceleration devices. Especially, the studies of the flow separation control techniques using the sweeping jet have been reported recently. However, most of these results are mainly contribution of the dynamic forces and the study on the flow mechanism produced by a sweeping jet has not been understood sufficiently. Especially, the vortex structure and flow mechanism formed by the interaction between the sweeping jet and the main flow have not been understood sufficiently. The purpose of the present study is to investigate the detailed vortex structure produced by the interaction between the sweeping jet from the Fluidic Oscillator and the main flow by a numerical simulation.
