| 摘 要： | 本文对液体内的声空化气泡的成长与破裂过程进行数值计算,得到各种情况下气泡壁的运动情况.通过对不同初始半径、不同频率下声空化气泡运动的计算,得到空化气泡半径小于共振半径,可以增强空化效果,而单一的增强声场的频率并不一定能加强声空化效果,为增强空化效果提供理论依据.研究各种信号作用下声空化气泡成长情况,明确方波信号激励下的...

| Abstract: | The numerical calculation of the development and collapse processes of the acoustic cavitation bubbles and the movements on the boundary on various conditions are presented.The calculation of the movements of the acoustic cavitation bubbles in different radius and frequencies conducts a conclusion that if the radius of the cavitation bubble smaller than the resonance radius, the effect of cavitation can be enhanced.However,it is uncertainty that if enhance the frequency of the sound field only.Various signa... |
