本文描述了一种新的声学整流效应现象,当Helmholtz共振腔内部声源以共振频率激振时,整流以一股湍流喷流形式发生。流动显示、热线和激光测量结合起来对此声学整流过程进行了研究,结果表明整流是由Reynolds应力作用产生的。
This article describes a new phenomenon of acoustic rectification, which occurs as a turbulent jet when the source of the Helmholtz resonator is excited at the resonant frequency. Flow visualization, hot wire and laser measurements combined the acoustic rectification process and the results show that rectification is caused by Reynolds stress.
