流路壁面の振動による周期的擾乱を与えた水平ニ平板後流の可視化実験

抄録

Two flat plates wake without reverse flow is very unstable and is affected by extremal disturbances.In this study，visualization of two flat plates wake was conducted to clarify the effect of periodic disturbances.The periodic disturbance is generated by vibrating the rubber wall. It was found that there are various flow patterns in the vortex formation process and the vortex breakdown process，and these flow patterns change greatly depending on the disturbance frequency.
