Taylor vortices versus Taylor columns

Spectral Theory of Taylor Vortices

Structural evolution of the Taylor vortices

We classify in this article the structure and its transitions/évolution of the Taylor vortices with perturbations in one of the following catégories: a) the Hamiltonian vector fields, b) the divergencefree vector fields, and c). the solutions of the Navier-Stokes équations on the two-dimensional torus. This is part of a project orient ed toward to developing a geometrie theory of incompressible...

Spirals vortices in Taylor-Couette flow with rotating endwalls.

A Hopf bifurcation with translational invariance has been widely considered as an appropriate model for the appearance of spiral vortices in counter-rotating Taylor-Couette flow. Our experimental work demonstrates that flow conditions close to the axial boundaries are responsible for the type of bifurcation scenario, i.e., either asymmetric pure traveling waves or more complex behavior, such as...

Model of convective Taylor columns in rotating Rayleigh-Bénard convection.

Observations, and laboratory and numerical studies, of fluid flows with strong rotation and thermal forcing often show long-lived convective Taylor columns (CTCs) which carry a large portion of the vertical heat and mass fluxes. However, owing to experimental and numerical challenges, these structures remain poorly understood. Here we present a nonlinear, analytical multiscale model of CTCs in ...
