Magnetic Dynamo Driven by Inertial Waves
A. Mishra, G. Mamatsashvili, M. Le Bars +2
We demonstrate, by studying precession-driven flows, that inertial wave hydrodynamic turbulence can drive a robust magnetic dynamo action. Motivated by the stronger damping of larg…

The effect of split endcaps on the flow dynamics in a tall Taylor-Couette setup
A. Mishra, P. Personnettaz, G. Mamatsashvili +2
The effects of axial boundaries, or endcaps are of fundamental interest in many Taylor-Couette (TC) flow experiments. A main challenge in those experiments has been to minimize the…

Strong and weak dynamo regimes in Taylor-Couette flows
A. Mishra, G. Mamatsashvili, F. Stefani
We reveal a nonlinear magnetic dynamo in a Taylor-Couette flow at small magnetic Prandtl numbers , which has been previously believed to exist only at higher $Pm\gtrsim 1…
