Ideal Plug-Flow Properties of Taylor Vortex Flow

Pattern selection in the absolutely unstable regime as a nonlinear eigenvalue problem: Taylor vortices in axial flow

“…However, at larger Re one observes stationary spirals and mixed flow patterns [26,25] in addition to the bifurcation of propagating spirals [25,[21][22][23][24]44]. The latter are predicted by the linear stability analysis to branch off the basic state at Re ≈ 20 [19,20,52].…”

“…Linear stability analyses of the basic state to traveling axisymmetric vortices were performed using various approximations, e. g. , for the narrow-gap limit, or simplified azimuthal velocity, or axial through-flow profiles [40], and later on for various aspect ratios fixed by the diameters of both cylinders [19,20,41,42]. Also, many experiments and comparisons with the theoretical predictions were done [21][22][23][24][25]28,29,[31][32][33][34][35]43,44].…”

Spatiotemporal Patterns in Liquid-Liquid Taylor-Couette-Poiseuille Flow

“…Most work on this problem, however, has been limited to either homogeneous single phase fluids with no applied axial flow (for exceptions, see Refs. [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].…”

Effect of the rotor shape on the mixing characteristics of a continuous flow Taylor-vortex reactor

“…Mixing in Taylor-vortex devices operated in continuous (axial) flow mode has also been the subject of numerous studies (Kataoka et al, 1975;Kataoka and Takigawa, 1981;Enokida et al, 1989;Pudjiono et al, 1992;Moore and Cooney, 1995;Giordano et al, 1998;Yim et al, 1998;Haut et al, 2003;Judat et al, 2004). In continuous flow mode, not only vortex segregation but also bypass effects and vortex slowdown can be observed.…”
