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

Funds: The project was supported by the Foundation of Science and Technology on Hydrodynamics Laboratory (9140C220204110C2203).
  • 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.
