Measurements of Radiated Noise in the Caltech High-Speed Water Tunnel. Part II. Radiated Noise from Cavitating Hydrofoils.

Abstract

This paper is the second part of a report on recent measurements of hydrodynamic noise in the Caltech High-Speed Water Tunnel. In the first part, results for noise radiated from fully wetted turbulent boundary layers were presented. In this part the results for cavitating flows are described. Because of the greater intensity of cavitation-produced noise, the signal to noise, ratio was much higher in these measurements than in the fully wetted case. Noise spectra were measured over a range of variations of flow velocity, cavitation number, and model configuration.
