概要 A visual study has been made of the flow around a circular cylinder performing sinusoidal oscillations in a uniform flow. The frequencies of the cylinder have been changed from 10 to 30Hz. When a cyli...nder has been oscillated normal to the uniform flow direction, the width of the wake behind the cylinder becomes large. As the result, the length of the twin vortices becomes large and the frequency of the vortex street in the wake becomes small. On the other hand, when the cylinder has been oscillated in a uniform flow direction, the flow in the wake behind the cylinder was accelerated by the secondary flow induced by the cylinder and the separated wake region has been disappeared.続きを見る
