RESUMO

Effects of various magnetic fields on thermocapillary-buoyant convection in an annular pool are investigated by three-dimensional numerical simulation, where the outer and inner walls are differentially heated. The computational results show that, under horizontal magnetic field, the number of azimuthal wave decreases with magnetic field intensity increase, and the induced electric current forms two closed circuits under a magnetic field of B0 = 0.5 T. Under an axial magnetic field, the azimuthal wave pattern shrinks to the vicinity of the inner wall gradually with increase in the magnetic field intensity, and the induced electric current forms one circular closed circuit under an axial magnetic field of B0 = 0.5 T. In general, the damping effect of an axial magnetic field is stronger than that of a horizontal magnetic field.
