摘要：
Low frequency pressure oscillations in open jet wind tunnels are produced by vortices shed from the nozzle exit coupled with several feedback mechanisms in the circuit. These undesired pressure fluctuations can cause structural vibrations, reduction of flow quality, and delays in delivery of newly-built wind tunnels. One effective method to mitigate this problem is incorporation of Helmholtz resonators in the wind tunnel circuit. In this paper important factors in the design of Helmholtz resonators for open jet wind tunnels are described and a specific design procedure is outlined. Finally, successful design and installation of Helmholtz resonators in several modern open jet wind tunnels is reported.
