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…
The effect of nutation angle on the flow inside a precessing cylinder and its dynamo action
V. Kumar, F. Pizzi, A. Giesecke +4
The effect of the nutation angle on the flow inside a precessing cylinder is experimentally explored and compared with numerical simulations. The focus is laid on the typical break…
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…
