EXPERIMENTAL STUDIES OF CAVITATION NOISE IN A FREE-JET TUNNEL

Abstract

The results of experimental studies on cavitation noise generated in the free-jet tunnel at St. Anthony Falls Hydraulic Laboratory in the period October 1960 to June 1961 are summarized. Two-dimensional test bodies of different shapes, such as a circular cylinder, wedge, and a TulinBurkhart hydrofoil were tested. Various types of cavitating flows, namely, transient cavities, steady-state cavities, and non-stationary cavities were covered. Special attention was given to the effect of ventilation on the intensity of cavitation noise. Effects of body size and the presence of a solid boundary were also investigated. (Author)
