Control of cavitating flows: A perspective

Abstract

This is a summary of our research on unsteady partial cavitation and ventilated partially and supercavitating flows with special emphasis on control strategies. We draw upon our experience with a variety of projects ranging from the experimental and numerical description of sheet/cloud cavitation to the control of high-speed supercavitating bodies. In addition, our numerical simulations of partially cavitating hydrofoils indicate that there is a regime where the potential exists for feedback control of gust-induced oscillations. These efforts are in the incubation stage. The purpose of this presentation is to provide our perspective on the problems and opportunities for control of cavitation and to encourage a healthy interchange of ideas at this workshop.
