Effect of magnetic field on the buoyancy and thermocapillary driven convection of an electrically conducting fluid in an annular enclosure
TLDR
In this paper, the effect of magnetic field on the combined buoyancy and surface tension driven convection in a cylindrical annular enclosure is studied. And the results reveal that, in tall cavities, the axial magnetic field suppresses the surface tension flow more effectively than the radial magnetic field.About:
