Simulating Current-Driven Magnetohydrodynamic Flows Using COMSOL Multiphysics® - Archived
Current-driven magnetohydrodynamic (MHD) flows have many applications, such as in liquid metal batteries, vacuum-arc remelting, arc welding, aluminum reduction cells, and more. Simulating them involves coupling electromagnetics (Maxwell's equations) with fluid dynamic equations (Navier–Stokes equations). This is possible using the AC/DC Module and CFD Module add-ons to the COMSOL Multiphysics® software.
Dr. Avishek Ranjan, professor at IIT Bombay, has used COMSOL Multiphysics® to simulate current-driven flow in a single fluid domain as well as in a practical geometry that has solid–fluid coupling present. The selection of methods, numerical schemes, and boundary conditions applied to the electromagnetic quantities is critical to achieve accurate results.
In this webinar, Dr. Ranjan will discuss how to model these flows, explain the computational challenges involved, and cover the advantages and flexibility that COMSOL Multiphysics® offers in selecting specific boundary conditions.
