We report on the mobility and orientation of finite-size, neutrally buoyant prolate ellipsoids (of aspect ratio $\Lambda=4$) in Taylor-Couette flow, using interface resolved numerical simulations. The setup consists a particle-laden flow between rotating inner stationary outer cylinder. simulate two particle sizes $\ell/d=0.1$ $\ell/d=0.2$, $\ell$ denoting major axis $d$ gap-width cylinders. vo...

We consider the motion of a viscous compressible and heat conducting fluid confined in gap between two rotating cylinders (Taylor–Couette flow). The temperature is fixed but not necessarily constant. show that problem admits time-periodic solution as soon ratio angular velocities rational number.

In the Taylor-Couette experiment on fluid flow between counterrotating cylinders, there is a bicritical point where the onset of instabilities to Taylor vortex flow (a steady-state bifurcation) and spiral vortex flow (a Hopf bifurcation) meet. The nonlinear mode interactions near this bicritical point are analyzed, exploiting the role of symmetry in the bifurcation theory. and with emphasis on ...
