• Three-dimensional numerical calculations have been performed on liquid-metal MHD flow through a circular pipe in the outlet region of a magnetic field. The continuity equation, the momentum equation and the induction equation have been solved numerically. The induction equation is derived from Maxwell's equations and Ohm's law in electromagnetism. The discretization of the equations is performed by the finite difference method, and the solution procedure follows the MAC method. Calculation results have shown that along the flow axis, i.e. the circular pipe axis, the pressure decreases steeply as a fully-developed MHD flow, drops more sharply in the magnetic-field outlet-region, and finally decreases slowly as a normal non-MHD flow. The flow velocity distribution changes from a flat profile of a fully-developed MHD flow to a parabolic profile of a non-MHD laminar flow in the outlet region of the magnetic field.
