摘要: Abstract A numerical study of three-dimensional (3D) MHD laminar flow in a short horizontal cylindrical annulus has been performed to characterize the impacts uniform axial magnetic field on both hydrodynamic and thermal behaviors. This configuration corresponds annular mold containing molten iron or low carbon steel electromagnetic casting (EMC). Complex nonlinear governing equations are solved numerically by means finite volume method based artificial compressibility algorithm. The induced electric potential caused is considered. Results show that typical 3D steady spiral arises symmetry breaking occurs under weak Ha − 3 8 π ≤ φ ), significantly affected field. results present work can be useful producing high-quality products control.
