Final Report on ONR Grant N00014-90-J-1828 (Case Western Reserve University)

Abstract

During the 1990 fiscal year, this project was transferred to the ONR- ARI on Bubbly Flows. Work completed or initiated during the course of this project to date includes: Studies of the dynamics of incompressible gas bubbles in time-dependent flows. We have carried out a combination of analytical and numerical studies that have identified conditions for bubble breakup in both steady and time dependent flows; the influence of bubble deformation on the natural oscillation frequency of various deformation modes; and the onset of chaotic oscillations of shape (that lead to breakup) in both periodic and quasi- periodic flows.
