Transition to magnetorotational turbulence in Taylor--Couette flow with imposed azimuthal magnetic field
A. Guseva, A. P. Willis, R. Hollerbach +1
The magnetorotational instability (MRI) is thought to be a powerful source of turbulence and momentum transport in astrophysical accretion discs, but obtaining observational eviden…
Low-dimensional representations of exact coherent states of the Navier-Stokes equations from the resolvent model of wall turbulence
Ati S. Sharma, Rashad Moarref, Beverley J. McKeon +3
We report that many exact invariant solutions of the Navier-Stokes equations for both pipe and channel flows are well represented by just few modes of the model of McKeon & Sharma…
The role of periodic orbits and bubbles of chaos during the transition to turbulence
S. Altmeyer, A. P. Willis, B. Hof
Starting with turbulence that explores a wide region in phase space, we discover several relative periodic orbits (RPOs) embedded within a subregion of the chaotic turbulent saddle…
