【摘要】 高速航行的舰船和水中载体造成物面空化是自然现象,可用基本的物理理论解释,用压力系数、空化数来描述,并在实验中验证。空泡、超空泡的减阻效应开创了舰船、水中兵器的速度新纪元,也给多普勒计程仪湿端安装带来了前所未有的困难。有必要对这一课题开展深入研究。更多还原

【Abstract】 High-speed ships and underwater carrier surface caused by cavitating is a natural phenomenon. It can be explained by basic physics theory and described by pressure coefficient and cavitating number. It can also be validated with experiments. Cavitation and supercavitation drag reduction effect ushered in a new era of ships and underwater weapon speed. At the same time it brings doppler wet end installed a unprecedented difficulties. So it is necessary to conduct in-depth research on this subject.更多还原
