Abstract

Direct simulation of 3D MHD liquid metal flows in the U-bend of DCLL blanket with flow channel insert (FCI) has been conducted based on electrical potential formula by using a consistent and conservative scheme, which can ensure the calculated current density conserve the charge and the calculated Lorentz force conserve the momentum. Compare study of the pressure and velocity distributions of liquid metal in the U-bend without external magnetic field or without FCI or with FCI are conducted in this paper. The results shows that: without external magnetic field, the flow structure is complex including the vortex generating at the turning; reverse flow happens at the end of FCI; the electrical conductivity of FCI plays a key role on MHD pressure drop, velocity distributions and so on. This work is the theoretical basis of optimizing blanket.
