摘要

在航行体高速出水过程中,其肩部的随体空泡在跨介质过程中溃灭产生的冲击载荷会对航行体的运动和结构产生影响甚至是破坏,但是航行体出水空泡发展溃灭的内在机理尚不明确。为了研究航行体出水空泡发展溃灭的动力学机理,探索可行的航行体出水空泡研究方法,本文采用边界元法,利用自编程程序,对航行体出水空泡进行模拟。计算得到航行体在出水过程中的空泡发展全过程,同时研究了空泡与自由面耦合作用下发生溃灭的作用机理。结果表明,采用边界元方法可以较为精确、有效地模拟空泡出水过程中的形态变化和动力学特性,准确描述空泡在近自由面与出水过程中发生的环状射流和同步溃灭现象,同时计算得到了环状射流砰击的水击压力,可以为航行体出水载荷预报计算提供参考。

Abstract

The impact load generated by the cavitation collapse during the process of crossing the medium can affect the motion and structure of a vessel, even causing damage, but the inherent mechanism of cavitation development and collapse during the water exit of the underwater vessel remain unclear. To investigate the dynamic mechanism of cavitation development and collapse during the process of high-speed water exit from a vessel's shoulder and explore feasible research methods of vessel water exit cavitation, the authors adopted the boundary element method and utilized a self-programmed code to simulate cavitation development and collapse during the water exit process. The complete process of cavitation development of underwater vessel during the water exit process is calculated, and the coupling mechanism between cavitation and free surface during collapse is studied. The results indicate that the boundary element method can accurately and effectively simulate the morphological changes and dynamic characteristics of cavitation during the water exit process, and accurately describe the ring-shaped jet and synchronous collapse phenomenon of cavitation near the free surface and during the water exit process. In addition, the study calculated the water impact pressure caused by the ring-shaped jet, which can provide a reference for the prediction and calculation of water exit loads of the vessel.
