本文提出了冲击波作用下消波池气室压力计算的方法。试验研究表明,当冲击波由管道进入消波池时,在池底形成气泡。随着气泡的膨胀,气室压力不断增加。根据流体力学和能量守恒的基本原理,并使用虚源(汇)法以近似满足边界条件,建立了两个微分方程式;求解此微分方程组即可算得气室最大压力值。计算结果与实验数据相当接近,其均方根误差在10%左右,足以满足工程的要求。中国人民解放军89003部队宗奎元、刘经论同志参加了本文的计算工作,谨此致谢。
In this paper, the method of calculating the pressure in the gas chamber of the wave-elimination cell under shock wave is presented. Experimental studies have shown that bubbles form at the bottom of the cell when the shock wave enters the cell through the pipe. As the bubble expands, the pressure in the chamber increases. According to the basic principles of fluid mechanics and energy conservation, and using the virtual source (sink) method to approximately meet the boundary conditions, two differential equations are established; the maximum pressure of the gas chamber can be calculated by solving the differential equations. The calculated results are quite close to the experimental data, and the root mean square error is about 10%, which is enough to meet the requirements of the project. People’s Liberation Army 89003 troops Zong Kuiyuan, Liu Jing comrades participated in the calculation of this article, I want to thank.
