空泡溃灭 meaning in Chinese
cavitation collapse
Examples
- Noise generation during the simultaneous collapse of two bubbles
双空泡溃灭及空化噪声的建模 - 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
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。 - Firstly it discusses the value , meaning , background and method of this topic . then it deducts the single - bubble sound pressure , spectrum of sound pressure , power spectrum . according to the real situation of traveling bubble cavitation noise around a schiebe body , the mathematical model of single - bubble collapse is selected , furthermore , the mathematical model of mass traveling bubbles without interference effect is established , and the multi - peaks and rebound phenomenon while bubbles collapse is also analyzed with statistical method
首先论证了本项研究的意义，价值，背景和方法，然后推出了单空泡辐射噪声声压，声压谱和功率谱，针对回转体流动泡空化噪声的具体情况，选择了双指数模型作为单空泡溃灭的数学模型，进一步建立了无干涉条件下的群泡辐射噪声的数学模型，并用统计的方法分析了空泡溃灭时的多峰值和反弹现象。 - 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
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。
