Direct simulation of 3D MHD flows in a duct with flow channel insert (FCI) relevant to R&D of fusion blanket has been conducted based on an electrical potential formula by using a consistent and conservative scheme. Comparison study of the pressure and velocity distributions of liquid metal in a poloidal duct with FCI, which has pressure equalization slot (PES) and pressure equalization holes (PEHs) with the same total area at the corresponding walls, is conducted. Both the PES and the PEHs have two kinds of locations, either in a Hartmann wall or in a side wall. 3D pressure and velocity distributions of the different cases have been given.
► We conduct 3D simulation of MHD flows in flow channel insert (FCI) with holes or slots. ► Pressure drop and velocity distribution are shown to illustrate the holes and plots effects on MHD flows of FCI. ► Pressure fluctuation for MHD flows in FCI with holes may introduce MHD instability.
