Generation of a magnetic field by convective flows in a rotating horizontal layer

The generation of a magnetic field by convective flows of a conducting fluid in a rotating plane layer is investigated numerically. The problem is considered in the complete three-dimensional nonlinear formulation. The sequence of temporal regimes that ensue as the Taylor number Ta increases from 0 (no rotation) to 2000 (the fluid motion is suppressed by rapid rotation) when the other parameters are fixed is studied. The Ta intervals on which bifurcations occur are found, and the breakdown and onset of symmetries in the attractors that arise is investigated.
