The combined effect of crucible rotation and applied magnetic field on hydrothermal wave was investigated through a three-dimensional simulation. The computational domain was a shallow annular pool filled with a silicon melt, subjected to a crucible rotation and a vertical static magnetic field. The thermocapillary flow along the free surface was considered. Governing equations of the system were solved numerically by the finite volume method. The efficiency of controlling hydrothermal wave with crucible rotation and magnetic field was assessed. Results showed that although the hydrothermal wave was completely suppressed under the effect of magnetic field alone, the optimum combination of the body forces induced by the applied crucible rotation and magnetic field provides a better control of the hydrothermal wave.
