Three-dimensional computation of turbulent natural convection in the presence of magnetic field

摘要: Numerical three-dimensional study is carried out on the turbulent natural convection of molten sodium (low Prandtl number fluid) in a cubic cavity heated from one vertical wall and cooled an opposing wall, with other walls thermally insulated. The exposed to external uniform magnetic fields, either horizontal perpendicular, (x-direction) or parallel direction (y-direction) directions (z-direction). field perpendicular gave smallest value average Nusselt largest value. On hand, was found be effective between these two extremes. effect laminar flow greater than that for two-dimensional at same intensity.
