FLOW SEPARATION, WAKE VORTICES AND PRESSURE DISTRIBUTION AROUND A CIRCULAR CYLINDER UNDER OSCILLATORY WAVES

Yuichi Iwagaki, Hajime Ishida

Abstract


Flow separation of a laminar boundary layer on the surface of a circular cylinder developed by monochromatic waves has been investigated both theoretically and experimentally, and next, characteristics of vortex formation and shedding have been discussed with Keulegan-Carpenter's number and Reynolds number, and finally, local depressions of the wave pressure around the cylinder induced by wake vortices have been examined in the experiment .

Keywords


slow separation; wake vortices; pressure distribution; cylinder; oscillatory waves
