Fast Dynamos in Spherical Boundary-Driven Flows
Fast Dynamos in Spherical Boundary-Driven Flows
We numerically demonstrate the feasibility of kinematic fast dynamos for a class of time-periodic axisymmetric flows of conducting fluid confined inside a sphere. The novelty of our work is in considering the realistic flows, which are self-consistently determined from the Navier-Stokes equation with specified boundary driving. Such flows can be …
