3d magneto-hydrodynamic analysis for Pb-Li flow inside LLCB TBM

The first wall (FW) of Indian LLCB TBM is cooled by high pressure helium gas, whereas LLCB TBM internals, such as the breeder plates, top and bottom plates are cooled by molten lead-lithium (Pb-Li), which enters the TBM from bottom inlet plenum after passing through a circular manifold region having several bends. Further Pb-Li flows through five parallel channels around four ceramic breeder cassettes and gets collected at the top plenum of TBM. It then flows downwards through the Pb-Li channel adjacent to the FW and finally exits the TBM through the bottom outlet plenum. As the LLCB TBM will be placed within the plasma-confining toroidal magnetic field,the electrically conducting Pb-Li encounters strong electromagnetic forces due to the MHD effects. As a consequence of this, velocity distribution as well as flow configuration of Pb-Li changes inside the LLCB TBM and an additional pressure drop occurs because of flow opposing MHD Lorentz force J×B
