Abstract
In order to generate low frequency acoustic wave and minish the ratio of the length to diameter, it is appropriate to instead the circular jet by annular jet as the high pressure gas power. So the larger diameter of jet and resonator are got in the condition of the same pressure and flux. Flow simulations have been performed in order to better understand the behavior of the powered resonance tube (PRT) driven by annular. Simulation results show the PRT can be excited by a high-speed annular jet, and produce low frequency high-amplitude dynamic pressures and acoustic emission. The compression wave and expansion wave generate and transmit into the resonance tube alternately in a cycle. So a cycle can be decomposed to two distinct stages of filling and evacuation. Pneumatic process in each cycle generally can be divided into four steps: compression wave introducing, Compression wave reflecting, expansion wave introducing, expansion wave reflecting. The two Compression wave phases are the filling process and the . two expansion wave phases are the evacuation process.
