Abstract: Pressure pulsations in a cavitating venturi were measured and investigated statistically. A classification method for the components of the pressure pulsations based on their statistical characteristics is here presented. The pulsations can be classified as of three basic categories: basic flow noise, cavitation bubblecollapse pulses, and cavitation associated low-frequency pressure fluctuations. Their distinctively statistical characteristics are presented, and a spectrum analysis for the low-frequency fluctuations is given to help explain their mechanism.
