Abstract
A study of the closed wakes behind large gas bubbles rising between two parallel plates reveals that they are elliptical in shape, rather than circular. Fitting an are of an ellipse, rather than a circle, to the curved upper surface of such a bubble eliminates a discrepancy between theory and experiment noted by Collins (1965a). Collins’ analysis of the effect of finite channel width is extended to the elliptical case, and the stability of the closed wake is examined.
