摘要

过去几十年来,冷凝水诱发的水锤事件一直是核工业关注的问题。随着无源反应堆设计的出现,人们开始关注这些系统中自然形成的汽穴。本文对过冷气泡腔内爆的几个方面进行了研究。本文将特别关注球形空腔内爆瞬态。利用雷利-普莱塞特方程的可压缩版本进行了数值范围计算。计算围绕预测两个关键参数,即峰值压力和净声波能量释放。这两个参数都与量化球形水锤事件的破坏潜力有关。

A Method for Estimating Acoustic Implosion Efficiencies for Collapsing Cavities in Nuclear Reactor Systems
For the last several decades, condensation induced water hammer events have been a concern i n the nuclear industry. With the arrival of passive reactor designs, concerns have arisen about the natural inception of vapor cavity formation in these systems. Several aspects of subcooled bubble cavity implosions are examined. In particular, this paper will focus on spherical cavity implosion transients. Numerical scoping calculations were performed with the compressible version of the Rayleigh-Plesset equation. The calculations revolved around predicting two key parameters, the peak pressure and the net acoustic energy release. Both of these parameters are relevant in quantifying the damage potential of a spherical water hammer event.
