Abstract:

In this program we are investigated the dynamics of cavitation as it occurs on or near rotating propulsors. While there are many different forms of cavitation on propulsors, we are concentrating our effort on understanding the flow processes resulting in limited event rate cavitation occurring in the vortical flows in the tip region of ducted propulsors. We completed the construction of a new recirculating water channel. We are examining the process of nuclie capture, cavitation, and noise production of vortex cavitation. We have been conducting experiments both at our laboratory at the University of Michigan and at the Naval Surface Warfare Center, Carderock Division. Our primary effort has been examining the tip leakage flow of a large ducted rotor in the 36 inch water tunnel at NSWC-CD. This experiment is conducted in cooperation with Dr. Jessup of NSWC.
