MEASUREMENTS OF RADIATED NOISE FROM CAVITATING HYDROFOILS

The present program of noise measurements is being conducted in the High Speed Water Tunnel at the California Institute of Technology. It is the intent of this program to measure the noise spectrum from hydrofoil models in the 2-D working section of the water tunnel and to determine the noise dependence upon cavitation number and flow velocity. Noise from several types of cavitation is being studied. The cavity generated on the leading edge of a hydrofoil at an angle of attack has been studied extensively. The cavity at the base of a wedge-shaped "supercavitating" hydrofoil has also been studied. A model is under construction for the measurement of noise from a tip vortex cavity.
