Écoulement de Couette Taylor diphasique

This paper presents the study of mutual interactions between dispersed and continuous phase in Couette Taylor flow. The introduction of the dispersed phase is obtained by ventilation or by pressure drop in an airtight chamber. In the first instabilities, the dispersed phase generate a modification of the flow state, the cavitating flow being moreover characterised by an advance to the third instability. The dispersed phase first stands along each of the apparent azimuthal waves as a string of individual bubbles located near the core of the Taylor cells and then migrates to the outflow regions near the inner cylinder.
