| 摘 要： | 利用流动显示的方法研究了高强声驻波管中的声流特付。结果指出,在高强声下(声压级大于160dB),驻波管中的声流特性与一般意义上的驻波声流特性差别很大。对该现象的认识有助于进一步了解高声强下的非线性效应。

| Abstract: | In this article, acoustic streaming in standing wave field of high-intensity is investigated using flow visualization method. The result points out that under the condition of high-intensity (the sound pressure level is larger than 160 dB), the characteristics of acoustic streaming are quite different with that in common sense of acoustic streaming in standing wave field. The recognization of this phenomena is helpful for further studying of nonlinear effects of high-intensity sound field. |
