Experimental results concerning separated twophase flow around a circular cylinder
Abstract
This paper deals with experimental results concerning pressure fluctuations on the surface of a circular cylinder immersed perpendicular to a twophase airwater bubble flow, and velocity fluctuations in the cylinder's separated flow region with respect to void fraction. It is shown that a critical twophase flow void fraction value exists to markedly classify flow characteristics: when the void fraction is less than the critical value, the flow structure resembles that of a singlephase fluid flow and, for a void fraction more than that value, this flow becomes very distinctive.
