Cavitation resonance: The phenomenon and unknown

Session A6

Abstract

This paper reviews the studies of cavitation resonance carried out by the authors. Cavitation-associated pressure fluctuation in hydraulic systems is an important phenomenon that affects the design, operation and safety of systems. Under certain conditions, the amplitude of one particular component of the fluctuations will become extremely high, causing a resonance. This phenomenon was firstly noticed and studied by one of the author (Li S C) in early 1980’s on cavitating Venturi flows. Later on, the cavitation resonance was also observed on a model turbine system. Currently, an investigation is being carried out on the Warwick Venturi by the authors of this paper with preliminary results also supporting the proposed hypothesis of the (macroscopic) mechanism. In this review, the observed phenomenon on these three flow systems is briefly introduced. The hypothesis of the (macroscopic) mechanism reduced from experimental obser-vations is then described and further investigations on the unknown aspects of the phenomenon are suggested.
