| 摘 要： | 空化泡在超声波的作用下其半径变化规律已经被实验所证实,如文献[1]。笔者在此基础上应用流体力学方法计算了超声空化泡在刚性壁面附近崩溃时对刚性壁的作用。计算表明,所得结果能很好地解释超声空化破碎薄铝箔的实验现象。

| Abstract: | The law of the variation of the radius of ultrasound micro-bubble under the effect of ultrasonic wave has been experimentally verified [1].In this essay,with the theory of hydromechanics we give a research into the acting force the ultrasound micro-bubble exerts on a rigid wall when it is breaking near the wall.Our result gives a good explanation of the experimental phenomenon observed in the experiment of breaking thin aluminum foil on the principle of ultrasonic cavitation. |
