## STUDY ON THE UNSTEADY VERTICAL CAVITY OF THE EXIT-WATER CAVITOR

• 摘要: 对空化器朝水面高速运动产生的非定常垂直空泡进行了理论研究. 建立了受水面和重力影响下的水下垂直空泡长度变化数学方程, 从方程中导出了非定常垂直空泡长度计算公式, 利用公式计算了空化器出水后空泡从脱落、收缩到溃灭的时间. 对带空化器的航行体, 公式还可以计算脱落空泡溃灭高压作用在航行体上的位置, 最后给出了避免溃灭高压作用在航行体上的条件和判据.

Abstract: The unsteady vertical cavity produced by the underwater cavitator moving rapidly towards the water surface is investigated theoretically. The mathematical model of the unsteady vertical cavity under water is presented; the formula of the vertical cavity length influenced by the gravity and water surface is derived, and the life span of cavity shedding from exit-water cavitator is also obtained from the formula. For the underwater body with cavitator, the acting position in the body of the high-pressure produced by the collapsed cavity is also calculated by the formula; moreover, the condition and criterion of keeping the underwater body from collapse high-pressure is presented.
