Plasma facing components pose significant challenges in magnetic confinement fusion systems, being exposed to high-energy neutrons, ions, heat fluxes, and mechanical stresses. A promising solution involves using liquid metal (LM) breeders, like pure lithium or lead-lithium alloy, flowing through complex blanket conduits within a strong magnetic field, leading to magnetohydrodynamic (MHD) effects. This study focuses on modeling and analyzing 2-D MHD flow of dual-coolant lead-lithium (DCLL) in open rectangular channels using ANSYS software. Computational Fluid Dynamics (CFD) methods simulate the behavior of electrically conductive liquids, separately modeling helium coolant and lead lithium eutectic. The objective is to analyze velocity and temperature profiles, specifically examining MHD effects on the lead lithium eutectic. By studying MHD flow in a dual-coolant lead-lithium system, this research aims to enhance understanding and optimize these systems for controlled thermonuclear fusion.
