Abstract

To quantify the interaction between the flow structures and the cavitating phase, the present experimental study focuses on the velocity measurements and spectral analysis by LDV of the liquid flow properties in a cavitating Couette Taylor flow. In this experiment, where the turbulent scales take place progressively, the bubbly phase is introduced in the gap by pressure drop and a particular attention is devoted to the determination of the effects of this bubbly phase on the properties of the flow by comparison between the single phase patterns and those observed in cavitating flow. This experimental work has highlighted the particular arrangement of the cavitating phase generated by the vortex pattern and the modification of the regimes existing in the single phase flow.
