Abstract:

Research on hydrodynamics of high speed vehicles in underwater launch process has a prominent engineering background, and contains typical frontier scientific issues. Relevant unsteady cavitating flow issues including instability and collapse of cavities, are of~crucial importance to the analysis of dynamic load and underwater launching vehicles' safety. In this paper, we first introduce the main scientific problems and the control parameters. Then we review the physical mechanisms on the development instability, collapse and control methods of unsteady fluid cavitation. Finally, remaining challenges and development~tendency for future research are given.

Key words: underwater launching, high speed hydrodynamics, cavitation stability, cavitation bubbles collapse, flow control by ventilation, load of fluid-structure interaction
