Abstract:

When a small low speed wind tunnel installed in a university was operated, a large vibration occurred. Solving this problem, the vibration at the diffusion cave with large vibration and noise around the diffusion cave were measured. As a result, it was clarified that this vibration and noise were due to karman vortex generated from the radiator installed in the diffusion cave. The sound field in the diffusion cave was firstly excited, after that the resonance was occurred.
