【摘要】 通过对忽略液体粘性等一些因素对空泡溃灭过程的影响,分析了空泡在收缩过程中,泡壁四周压强的变化,得出空泡在此不均匀压强的合力作用下向刚性边壁运动的轨迹方程。为确定空泡溃灭点,并由此确定空蚀对固壁的破坏作用作了探索性工作。更多还原

【Abstract】 Neglecting the influence of some factors,such as liquid’s viscidity etc.,upon the process of empty bubble breaking,the authors analyze the pressure variation on bubble’s wall in all directions when it shrinks,and deduce the equation of its moving track towards the rigid side wall under the function of asymmetry pressure.In order to make sure the point where an empty bubble breaks and breakage function on the solid wall due to cavitatin,some exploration work is performed.更多还原
