Transient growth in Taylor-Couette flow [PDF]
Physics of Fluids, 2002 Transient growth due to non-normality is investigated for the Taylor-Couette problem with counter-rotating cylinders as a function of aspect ratio eta and Reynolds number Re. For all Re < 500, transient growth is enhanced by curvature, i.e.

Transient Turbulence in Taylor-Couette Flow [PDF]
Physical Review E, 2009 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 ...

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.

Inviscid damping and the asymptotic stability of planar shear flows in the 2D Euler equations [PDF]
, 2014 We prove asymptotic stability of shear flows close to the planar Couette flow in the 2D inviscid Euler equations on $\Torus \times \Real$. That is, given an initial perturbation of the Couette flow small in a suitable regularity class, specifically ...
