Abstract
This paper presents a summary of some recent observations of the interaction between individual traveling cavitation bubbles and the nearly solid surface. These reveal a complex micro-fluid-mechanics associated with the interaction of the bubble with the boundary layer, the surface and the large pressure gradients exterior to the boundary layer which normally occur in the vicinity of a minimum pressure point. The details are important because they affect how the bubble collapses and therefore influence the noise produced and the damage potential of the cavitating flow. We present data showing how the noise from an individual event can be affected by these interaction effects. Since the scaling of cavitation phenomena is always an important issue we also describe the results of some experiments carried out to investigate the scaling of these interaction effects.

Additional Information: | The author acknowledges the major contributions made to this research by students and former students at the California Institute of Technology and, in particular, Steven L. Ceccio (now at the University of Michigan), Sanjay Kumar (now at the Massachusetts Institute of Technology), and Yan Kuhn de Chizelle. I also appreciate the help given by Douglas Hart (now at the Massachusetts Institute of Technology) and Zhenhuan Liu. The experiments in the D.T.R.C. Large Cavitation Channel would not have been possible without the help of W. M. Morgan, E. Rood, Young Shen, Scott Gowing, James Blanton, Bob Etter, and Po-wen Yu. The research was supported by ONR under contracts N00014-91-J-1295 and N00014-91-J-1426 and by the David Taylor Research Center. While I was preparing this manuscript in Kyoto, Japan, my teacher and friend, Arthur Arnold, passed away in a village halfway around the world. This paper is dedicated to him; I will miss him dearly. |
