초록

Flow control of flow field is essential to design efficient elements relating to fluid machineries. In this study, the flow characteristics of rectangular prism with throughflow at different aspect ratio was investigated to flow control. A particle image velocimetry technique was employed to obtain detailed measurements at throughflow-velocity-based Reynolds numbers. As a results, the throughflow disturbs the development of vertical velocity component and decreased the vortex size.
