Bifurcation phenomena in Taylor–Couette flow in a very short annulus with radial through-flow [PDF]
Scientific Reports, 2022 In this study, the non-linear dynamics of Taylor–Couette flow in a very small-aspect-ratio wide-gap annulus in a counter-rotating regime under the influence of radial through-flow are investigated by solving its full three-dimensional Navier-Stokes ...

Measuring non-extensitivity parameters in a turbulent Couette-Taylor flow [PDF]
Physical Review E, 2000 We investigate probability density functions of velocity differences at different distances r measured in a Couette-Taylor flow for a range of Reynolds numbers Re. There is good agreement with the predictions of a theoretical model based on non-extensive

Hydromagnetic Taylor--Couette flow: wavy modes [PDF]
, 2002 We investigate magnetic Taylor--Couette flow in the presence of an imposed axial magnetic field. First we calculate nonlinear steady axisymmetric solutions and determine how their strength depends on the applied magnetic field.

Second-Order Phase Transition in Counter-Rotating Taylor–Couette Flow Experiment [PDF]
Entropy, 2020 In many basic shear flows, such as pipe, Couette, and channel flow, turbulence does not arise from an instability of the laminar state, and both dynamical states co-exist.

Non-axisymmetric instability of shear-banded Taylor-Couette flow [PDF]
, 2012 Recent experiments show that shear-banded flows of semi-dilute worm-like micelles in Taylor-Couette geometry exhibit a flow instability in the form of Taylor-like vortices.

Multiplicity of states in Taylor-Couette flow of a dense granular gas [PDF]
EPJ Web of Conferences, 2021 Molecular dynamics simulations with a purely repulsive Lennard-Jones potential and a normal damping force is used to simulate the granular flow in the annular region between two differentially-rotating cylinders, called the Taylor-Couette flow.
