Turbulent Kinematic Dynamos in Ellipsoids Driven by Mechanical Forcing
Turbulent Kinematic Dynamos in Ellipsoids Driven by Mechanical Forcing
Dynamo action in planetary cores has been extensively studied in the context of convectively-driven flows. We show in this letter that mechanical forcings, namely tides, libration and precession, are also able to kinematically sustain a magnetic field against ohmic diffusion. Previous attempts published in the literature focused on the laminar …
