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…
One-winged butterflies: mode selection for azimuthal magnetorotational instability by thermal convection
A. Mishra, G. Mamatsashvili, M. Seilmayer +1
The effects of thermal convection on turbulence in accretion discs, and particularly its interplay with the magnetorotational instability (MRI), are of significant astrophysical in…
Non-axisymmetric modes of magnetorotational and possible hydrodynamical instabilities in the upcoming DRESDYN-MRI experiments -- linear and nonlinear dynamics
A. Mishra, G. Mamatsashvili, F. Stefani
The quest for an unambiguous detection of magnetorotational instability (MRI) in experiments is still ongoing despite recent promising results. To conclusively identify MRI in the…
Nonlinear evolution of magnetorotational instability in a magnetized Taylor-Couette flow: scaling properties and relation to upcoming DRESDYN-MRI experiment
A. Mishra, G. Mamatsashvili, F. Stefani
Magnetorotational instability (MRI) is the most likely mechanism driving angular momentum transport in astrophysical disks. However, despite many efforts, a conclusive experimental…
From helical to standard magnetorotational instability: predictions for upcoming liquid sodium experiments
A. Mishra, G. Mamatsashvili, F. Stefani
We conduct a linear analysis of axisymmetric magnetorotational instability (MRI) in a magnetized cylindrical Taylor-Couette (TC) flow for its standard version (SMRI) with a purely…
