The jet is controlled by a circularvortex chamber, and self exited oscillation occurs due to a pressure difference between the left and right parts of vortex chamber.
该装置利用环形涡腔对射流进行控制，利用涡腔的左、右腔的压力差产生自激振荡。

Besides, the present experiment has verified one previous discrete vortex model of the acoustic nonlinearity of a circular orifice.
此外实验结果还验证了一种微园孔声学非线性效应离散涡模型的合理性。
