Time dependent multimode hexagonal magnetoconvection
Abstract
The time-dependent multimode equations for magnetoconvection are solved numerically for a range of parameter values and cell sizes. The solutions demonstrate the existence of nonlinear interactions between the different scales of motion and show how the induced magnetic field is concentrated into the smaller length scale. The generation of mean kinetic and magnetic helicity occurs at low Prandtl number, a result which has significant physical interpretations in the solar situation. The results indicate that helicity is an important aspect of magnetoconvection in the sun.
