To make clear the stochastic (random) behavior of cavitation desinence, we statistically analyzed the acoustic pressure pulses associated with the cavitation, and defined the desinence by introducing the threshold level selected for the pulse-detection and the control parameters, such as the mean desinent cavitation number, σ̄d , the standard deviation of random variable, σ̂d , and those of the time interval between successive pulses. It is shown here that stochastic behavior takes place considerably in desinence, and varies significantly with the random quantities, as well as the air saturation rate of water.
