RT Journal Article ID 330a115b0842fc6e A1 Chen, Shengtao A1 Hu, Dapeng A1 Chen, Zuzhi A1 Dai, Yuqiang A1 Liu, Runjie A1 Zhu, Che T1 Theoretical and Numerical Investigation of Oscillation and Switch in a Sonic Oscillator JF International Journal of Fluid Mechanics Research JO FMR YR 2007 FD 2007-04-23 VO 34 IS 2 SP 115 OP 128 AB 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.
