MHD flow in a prototypical manifold of DCLL blankets (KIT Scientific Reports ; 7673)

Critical issues for the feasibility of dual coolant lead lithium blankets are large pressure drop and flow imbalance in parallel ducts due to 3D induced electric currents and 3D magnetohydrodynamic (MHD) phenomena that occur in liquid metal manifolds. In the present work we simulate MHD flows in a manifold where the liquid metal is distributed from a single duct into three parallel channels. The aim is identifying sources of flow imbalance, predicting velocity and pressure distribution.
