Cavity flow tones in water
Measurements of tones generated by flow over cavities were conducted in the ARL Penn State small water tunnel. The frequency dependence of cavity tones on the flow velocity and the size of the cavity opening in the streamwise direction are presented and discussed. Measured cavity wall vibration leve...

| Zusammenfassung: | Measurements of tones generated by flow over cavities were conducted in the ARL Penn State small water tunnel. The frequency dependence of cavity tones on the flow velocity and the size of the cavity opening in the streamwise direction are presented and discussed. Measured cavity wall vibration levels, unsteady pressure levels inside the cavity, and flow visualization are used to analyze generating mechanisms for cavity tones and Helmholtz resonances. |
