“…[3][4][5]) or to liquid-solid systems [6,7]. Little is known about the effects on the hydrodynamic structure of adding a second immiscible liquid phase in the presence of an applied axial flow, even though such systems are employed as liquid-liquid extraction devices with high interphase mass-transfer efficiencies [8][9][10]. In one of the few published studies of liquid-liquid Taylor-Couette flow, the presence of the dispersed phase was found to increase the circumferential mixing [11].…”

“…We show that hysteresis may occur between consecutive regimes depending on flow history, and this may have a significant effect on mixing for a given Reynolds number. Annular centrifugal contactors based on Taylor-Couette flow geometry have a great potential in chemistry, hydrometallurgy and, since the prior works of Davis and Weber (1960), in the nuclear industry where they are particularly suitable for small-scale studies of solvent extraction processes. Since the pioneering work of Taylor (1923), Taylor-Couette flow has been extensively studied due to its nonlinear dynamics.…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract The flow and mixing in a Taylor-Couette device have been characterized by means of simultaneous particle image velocimetry and planar laser-induced fluorescence (PLIF) measurements. Concentration of a passive tracer measurements was used to investigate mixing efficiency for different flow patterns (from steady Taylor vortex flow to modulated wavy vortex flow, MWVF). Taylor-Couette flow is known to evolve toward turbulence through a sequence of flow instabilities. Macroscopic quantities, such as axial dispersion and mixing index, are extremely sensitive to internal flow structures. PLIF measurements show clear evidences of different transport mechanisms including intravortex mixing and tracer fluxes through neighboring vortices. Under WVF and MWVF regimes, intravortex mixing is controlled by chaotic advection, due to the 3D nature of the flow, while intervortex transport occurs due to the presence of waves between neighboring vortices. The combination of these two mechanisms results in enhanced axial dispersion. We show that hysteresis may occur between consecutive regimes depending on flow history, and this may have a significant effect on mixing for a given Reynolds number.
