The Effect of Free Stream Turbulence on the Coherent Structures in the near Wake of a Circular Cylinder
원주 후류의 응집구조에 대한 자유흐름 난류강도의 영향
Abstract
The effect of free stream tubulence on the coherent structure in the near wake of a circular cylinder was investigated by a conditional sampling technique. The measurements were made from C.T.A. with hot wire I-probe and a Split-film sensor. Contours of phase-averaged velocity and vorticities were presented and discussed. It was found that the value of the vortex strength increased with increasing free stream turbulence which can enhance the roll-up of the shear layer.
