水下航行体通气超空泡内压强分布实验研究
Experimental investigation of pressure distribution in ventilated supercavity of underwater vehicle model
摘要
Abstract
A series of experiments about supercavitating flow around underwater vehicle are conducted in a high-speed cavitation water tunnel to investigate the pressure distribution in the supercavity and the properties of rear flow field near the supercavity. The supercavity is filled by air and is related to artificial or ventilated cavity to form supercavitating flow at low speed (V=10～20 m/s). The pressure distribution in the supercavity was found by analyzing and measuring the pressure of several places in supercavity under conditions of various ventilation rate, the hydrostatic pressure p∞ and so on. The result indicates that the pressure in supercavity changes along the stream direction. The pressure gradient at rear of cavitation changes strongly, so the vibration re-entrant jet is caused. Further the re-entrant jet affects the motion stability of underwater vehicle.关键词
