Abstract : Recent investigations of the fundamental aspect of cavitation damage have indicated the importance of asymmetric bubble collapse. This investigation is an effort to theoretically and experimentally justify the role of asymmetric bubble collapse in cavitation damage. The theoretical investigation employs a combined Eulerian and Lagrangian computer code capable of following the collapse of a bubble much further than previous perturbation techniques. The experimental investigation is concerned with the development of a specialized spark camera with a maximum framing rate of 1,000,000 frames per second and a spatial resolution higher than any other camera presently available at this laboratory.
