Abstract
The Flowfield characteristics of a square prism having a detached splitter plate at the wake region were investigated by visualization of the flow field using PIV. The experimental parameters were the width ratios(H/B=0.5~1.5) of the splitter plate to the prism width and the gap ratios (G/B=0~2) between the prism and the splitter plate. As the results the Strouhal number measured at the wake region of the detached splitter plate was decreased with the width ratio and the gap ratio. The clockwise vortex at the upside of the splitter plate and counterclockwise vortex at the downside were represented, the size of these vortices were increased with the width of the splitter plate. The reverse flow was represented at the wake region of the square prism having a detached splitter plate, the size of this reverse flow was increased with the width of the splitter plate.
