The role of magnetic boundaries in kinematic and self-consistent magnetohydrodynamic simulations of precession-driven dynamo action in a closed cylinder
André Giesecke, Mike Wilbert, Ján Šimkanin +2
We numerically examine dynamo action generated by a flow of an electrically conducting fluid in a precessing cylindrical cavity. We compare a simplified kinematic approach based on…
The global flow state in a precessing cylinder
André Giesecke, Tobias Vogt, Federico Pizzi +4
We examine the fluid flow forced by precession of a rotating cylindrical container using numerical simulations and experimental flow measurements with ultrasonic Doppler velocimetr…
Dynamo action driven by precessional turbulence
V. Kumar, F. Pizzi, G. Mamatsashvili +3
We reveal and analyze an efficient magnetic dynamo action due to precession-driven hydrodynamic turbulence in the local model of a precessional flow, focusing on the kinematic stag…
High dimensional tori and chaotic and intermittent transients in magnetohydrodynamic Couette flows
Ferran Garcia, Jude Ogbonna, André Giesecke +1
The magnetised spherical Couette (MSC) problem, a three dimensional magnetohydrodynamic paradigmatic model in geo- and astrophysics, is considered to investigate bifurcations to hi…
Numerical and theoretical framework for the DRESDYN precession dynamo experiment
F. Pizzi, A. Giesecke, J. Simkanin +3
The upcoming DRESDYN (DREsden Sodium facility for DYNnamo and thermohydraulic studies) precession experiment will test the possibility to achieve magnetohydrodynamic dynamo action…
Interplay between geostrophic vortices and inertial waves in precession-driven turbulence
F. Pizzi, G. Mamatsashvili, A. J. Barker +2
The properties of rotating turbulence driven by precession are studied using direct numerical simulations and analysis of the underlying dynamical processes in Fourier space. The s…
