PIV analysis of vortex shedding behind a circular cylinder with a splitter plate asymmetrically arranged
Details
The wake behind a circular cylinder (diameter d) with a long splitter plate inserted is investigated experimentally in a water tank at Re=1.12×10^4. The splitter plate is traversed at three levels (Z/d=0, 0.5, 1.0). As the splitter plate is shifted upstream horizontally, the base suction coefficient increased gradually, but it falls critically at a certain position depending on Z/d. To make clear the mechanism of the critical change, PIV measurements are conducted for pre- and post-critical regime. It is found that the stream pattern changes depending on level Z.
