摘要:
采用定点测量声压的方法,在圆柱形反应器中,将水听器在不同功率设置下间隔一定距离测量声压.结果表明,在圆柱形声场中,声压随功率增加非线性增加,且声压分布呈现一定规律,即x、y轴声压为对称分布,声波沿z轴方向衰减.从而得到了圆柱形反应器的声场分布特性,界定空化发生的较强区域.

Abstract:
The sound field distribution of cylindrical cell is studied by the fixed-point measurement with different power levels. The results show that the increase of the acoustic pressure is nonlinear with increase of the power, the sound pressure distribution is symmetrical at x-axis and y-axis and is attenuate along the z-axis. Finally, the characteristic of acoustic field distribution in the cylindrical cell is obtained and the strong region of cavitation activity is found.
