Design of the acoustic spectrometer for the measurement of the spectrum of cavitation bubbles in water and hydraulic oil
Müller, M. ; Zima, Patrik ; Maršík, František
The article deals with the design of the experiment for the measurement of the spectrum of cavitation bubbles in water and hydraulic oil. Bubbles of different sizes tend the attenuate most efficiently the excitant acoustic frequency, which is close to their own resonance frequency. The acoustic response of the flowing bubbles to several different excitation frequencies enables to determine the number density of bubbles. The result of the analysis is a system of integral equations. The solution of the systems yields the size spectrum of the bubbles.
