STABILIZING EFFECTS OF MAGNETIC FIELD ON THE THERMAL CONVECTION FLOW IN A CONDUCTING FLUID
导电流体热对流中磁场的致稳作用

MHD equations of the thermal convection flow in a conducting fluid is derived and a numerical simulation is presented for the thermal convection flow in the semiconductor crystal growth under a vertical magnetic field. Computational results show that oscillations and multiccll flow structure with separation at wall are effectively suppressed by the magnetic field with an appropriate strength, and that the stabilizing effects of magnetic field on the thermal convection flow increase with Hartmann number increasing.
