Abstract: A periodic and oscillatory flow state in a sonic oscillator is studied in detail. In this paper, the physical model of a sonic oscillator is set up to demonstrate the flow state. Detailed theoretical analysis is made. Numerical simulation of the switch of the jet flow in a sonic oscillator is also done. Emphasis is placed on the factors affecting the switch of the jet flow. Both the momentum supplement to the low-pressure vortex area and the pressure wave in the controlling pipe are contributing. © 2007 Begell House, Inc.
