Abstract
Experimental investigations on the discrete frequency noise and flow around a flat plate were carried out. Each cross section of the leading and tail edges of the flat plate was a semi-circle and tripping-wires (T. W.) were set on the both surfaces. The length and thickness of the flat plate was 80mm and 10mm. respectively. The diameter of the tripping wire was 2mm. The Reynolds number based on the thickness ranged from 1.2×(10)4 to 3.1×(10)4. The effect of the position of the tripping wires on the discrete frequency noise and the fluid flow around the flat plate was investigated. It was found that : the discrete frequency noise was reduced by T. W., and Γf (Γ : circulation, f : vortex shedding frequency) is one of the control factors of the discrete frequency noise.
