Abstract

This experimental study is conducted to investigate effects of a splitter plate, which is set on the back side of a square prism in the uniform flow, The Reynolds number is 1.44 104 based on the width of the square prism. The measurement of velocity vector and pressure distribution are carried out 4 cases of length in the range of 0.5L to 2.0L with 0.5L interval and 3 cases of position at 0L, 0.25L, 0.5L. Flow visualization is also executed by smoke-wire method to understand the mechanism of vortex formation. The results show the strong vortex shedding patterns and drags are decreased effectively, when the position of splitter plate is 0L. And the drag reduction rate is in inverse proportion to the splitter plate length
