title = "Cavitating Orifice: Flow regime transitions and low frequency sound production",
abstract = "Detailed data are provided for the broadband noise in a cavitating pipe flow through a circular orifice in water. Experiments are performed under industrial conditions, i.e., with a pressure drop varying from 3 to 30 bars and a cavitation number in the range 0.10 = s = 0.77. The speed of sound downstream of the orifice happens to vary spontaneously for a given set of hydraulic conditions. In the intermediate {\textquoteleft}developed cavitation{\textquoteright} regime, whistling associated with periodic vortex shedding is observed. In the {\textquoteleft}super cavitation{\textquoteright} regime, a vapor cloud develops itself and the whistling disappears. The broadband noise in each regime is presented and its dimensionless representation is discussed.",
