主流中に吹出すSweeping jetが作り出す壁面近傍の渦構造

抄録

A fluidic oscillator generates a sweeping jet with high frequency and large amplitude and is characterized by its capability for jet ejection over a wide range and for fluid oscillation by an internal structure that eliminates the need for a drive unit. Recently, the sweeping jet from the fluidic oscillator has attracted attention as an active flow control device. However, there have been no studies on the macro-scale flow structure of the sweeping jet from the fluidic oscillator or the flow mechanism for active flow control. The purpose of the present study is to clarify the macro-scale vortex structure produced by the interaction between the sweeping jet and the main flow by using a numerical simultion.
