Stably stratified Taylor–Couette flows
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023 Stably stratified Taylor–Couette flow has attracted much attention due to its relevance as a canonical example of the interplay among rotation, stable stratification, shear and container boundaries, as well as its potential applications in geophysics and astrophysics.

Continuous Synthesis of 2-Methoxyhydroquinone from Vanillin in a Taylor-Couette Disc Contactor. [PDF]
ChemSusChemThis study investigates continuous synthesis of 2‐methoxyhydroquinone (MHQ) from vanillin in a Taylor‐Couette disc contactor (TCDC). The TCDC, a stirred column reactor utilizing Taylor vortices for intense mixing, achieved efficient phase separation and hydraulic stability.

Routes to turbulence in Taylor–Couette flow
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023 Fluid flows between rotating concentric cylinders exhibit two distinct routes to turbulence. In flows dominated by inner-cylinder rotation, a sequence of linear instabilities leads to temporally chaotic dynamics as the rotation speed is increased. The resulting flow patterns occupy the whole system and sequentially lose spatial symmetry and coherence ...

Transient turbulence in Taylor-Couette flow [PDF]
Physical Review E, 2010 Recent studies have brought into question the view that at sufficiently high Reynolds number turbulence is an asymptotic state. We present the first direct observation of the decay of turbulent states in Taylor-Couette flow with lifetimes spanning five orders of magnitude. We also show that there is a regime where Taylor-Couette flow shares many of the

Subcritical Equilibria in Taylor-Couette Flow [PDF]
Physical Review Letters, 2014 Nonlinear equilibrium states characterized by strongly localized vortex pairs are calculated in the linearly stable parameter region of counterrotating Taylor-Couette flow. These subcritical states are rotating waves whose region of existence is consistent with the critical threshold for relaminarization observed in experiments.

Numerical Turbulent Flow Analysis through a Rotational Heat Recovery System
Energies, 2022 Herein, hydrodynamic analysis from a large-eddy simulation in Couette–Taylor–Poiseuille (CTP) geometry is numerically investigated. The present geometry is inspired by a previous experimental work in which heat transport phenomena were investigated in a ...

Stratified Taylor–Couette flow: nonlinear dynamics [PDF]
Journal of Fluid Mechanics, 2021 A series of experiments on stratified Taylor–Couette flow in short aspect ratio wide-gap annuli found an intriguing and not-well-understood dynamics: nonlinear coherent structures appearing and disappearing periodically, along with density layering reminiscent of staircase profiles. A detailed numerical study is presented of the nonlinear dynamics near
