Dynamics of ferrofluidic flow in the Taylor-Couette system with a small aspect ratio
Sebastian Altmeyer, Younghae Do, Ying-Cheng Lai
We investigate fundamental nonlinear dynamics of ferrofluidic Taylor-Couette flow - flow confined between two concentric independently rotating cylinders - consider small aspect ra…

Transition to turbulence in ferrofluids
Sebastian Altmeyer, Younghae Do, Ying-Cheng Lai
It is known that in classical fluids turbulence typically occurs at high Reynolds numbers. But can turbulence occur at low Reynolds numbers? Here we investigate the transition to t…

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…
