A jet in cross flow is one of typical phenomena in fluid engineering and many studies about this flow field have been already reported. On the other hand, a sweeping jet produced by a fluidic oscillator has a high frequency and a large amplitude and is attracted attention from the viewpoint of an active flow control in recent years. However, the studies on sweeping jet in cross flow have not been understood sufficiently and the detailed flow structures and vortex structures have not clarified. The purpose of the present study is to clarify the detailed flow structures in the sweeping jet in cross flow by using a numerical simulation. Especially, the authors focus on the flow structures and its dynamic behaviors formed by an interaction between the sweeping jet and main flow near the outlet of the sweeping jet.
