【Abstract】

<正>The process of vortex rings impinging on a fixed wall is experimentally investigated by using flow visualization and particle image velocimetry(PIV) methods.The vortex rings are generated by a synthetic jet actuator from a circular orifice.It is found that the vortex ring of the first period increases its diameter as it ap-
