Abstract: Design studies are described for two recently completed large scale hydroacoustic test facilities (one of which is the world’s largest). These recirculating water tunnels have a different ...

Abstract: The St. Anthony Falls Hydraulic Laboratory has been involved in the hydrodynamic design of large cavitation facilities, which require a high performance axial flow pump that is cavitation free ...

Abstract: A study has been carried out to determine various aspects of the flow physics of a supercavitating vehicle at the Saint Anthony Falls Laboratory (SAFL). For the experimental work presented ...

Abstract: This paper summarizes recent research on the relation between boundary layer flow, tip vortex structure for a finite span wing, and cavitation. Three hydrofoils of elliptic planform of aspect ...

Abstract: A relatively high amplitude, discrete tone is radiated from fully developed tip vortex cavitation under certain conditions. The phenomenon of the “singing vortex” was first reported by Higuchi ...

Abstract: Tip vortex cavitation noise was experimentally investigated utilizing hydrofoils with an elliptic planform. The noise was monitored by an array of hydrophones. A variety of cavitating conditions ...

Abstract: This project was initiated as part of a new research and development focus to improve hydropower generation. One aspect of the problem is severe cavitation erosion which is experienced when ...
