Abstract

New simulations of powered resonance tubes (PRT) have been performed at two Reynolds numbers that differ by a factor of 10. The lower Reynolds results show strong regularity with some disorder showing up in the higher Reynolds number cases. Remarkably the simulations show that the dominant frequencies, amplitude and directivity of the PRT actuator output field are largely unaffected by the factor of 10 increase in Reynolds number considered here. However, the increase in Reynolds number is shown to substantially affect the width of the resonance peaks, and the vorticity distributions and flow details more generally. The effort to integrate simulations, theory, and experiment has been fruitful. There is general agreement between these three methods in terms of the frequency, amplitude, and directivity of the actuator output field, to the extent that they have been examined.
