| Title | NUMERICAL AND EXPERIMENTAL STUDY OF 3D LIQUID METAL MHD FLOW IN A RECTANGULAR FLOW PATH IN PRESENCE OF A PHYSICAL OBSTRUCTION |
| Abstract | In the liquid breeder blankets, the interaction of the electrically conducting fluid with the strong magnetic field () induces electric currents () and electromagnetic forces that influence velocity and pressure distribution in the blanket. Due to the Lorentz force (?) additional magneto hydrodynamic (MHD) pressure drop occurs. The MHD issues can affect the heat transfer and tritium breeding, flow distribution among the coupled channels, and result in significant pressure drops. The three major MHD issues are electromagnetic coupling, multichannel flow behavior, and liquid metal (LM) flow past obstructions. The complex 3D MHD phenomena occurs when there is any change in the flow channel geometry such as bends, expansions, contractions, and presence of obstacle in the flow path of liquid metal. Internal components of the liquid breeder blankets such as neutron diagnostics pipes, helium pipes for tritium extraction and water cooling pipes present in the liquid breeder blanket may physically block the flow path of LM, may alter the flow patterns of LM, and affect heat transfer, increase the pressure drop. Therefore, it is important to study the liquid metal MHD flow in the presence of a physical obstacle in the flow path of liquid metal. The present work is mainly focused on 3D thermo-fluid MHD studies in a model flow geometries having a physical obstacle in the form of hollow pipe in the flow path of Pb-Li. Both simple single rectangular flow channel and complex multichannel model flow geometry have been considered for the study. |
