Time frequency characteristics of the vibroacoustic signal of hydrodynamic cavitation

Abstract:

A theoretical analysis and experimental results are presented of the time-frequency characteristics of hydrodynamic cavitation signals. Because of the limitation of the frequency bandwidth of the data acquisition system and the random nature of cavity collapses, the signal consists of transient burst waveforms. The acoustic pulses from collapses in close time proximity mix together and form transient oscillatory bursts. The local oscillation frequency of a burst is related to either the time ...
