Switch of Jet Flow in a Sonic Oscillator
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. Under Coanda effect, the jet flow will attach to one side of the wall, and then starts oscillating. Two factors affect the oscillation. Both the momentum supplement to the low-pressure vortex area and the pressure wave in the controlling pipe are contributing.
