摘要：

Effects of magnetic fields on natural and Marangoni convections in a two-dimensional rectangular open boat were studied numerically. Convective velocities in magnetic fields depend on the Marangoni number, the Grashof number, physical properties, direction of the applied magnetic field and strength of magnetic field. For suppression of natural convection, either a horizontal (perpendicular to gravity) or a vertical (parallel to gravity) magnetic fields is effective. For suppression of Marangoni convection, the vertical magnetic field is more effective than the horizontal magnetic field.
