Abstract

Cavity would be formed at low pressure zone behind the cavitator of the high speed under water vehicle. Five kinds of supercavitating flow by different cavitator were simulated by two-dimensional axis-symmetry method. Volume drag coefficient was employed to describe the drag reduction ability of different cavitator. General rule of volume drag coefficient was obtained. An algebraic formula was fitted by the result of simulation. The paper can be a reference for investigation and design of under-water supercavitating vehicle.

Key words： cavitator; supercavitation; volume drag coefficient; numerical simulation
