The talk will be on the experiences of Prof Eswaran's team in developing a numerical code to solve such problems. It will discuss the basic equations and approximations made in liquid metal MHD, the strategies that are used to handle complex geometries, and variable-directional magnetic fields of extremely high strength (Ha ~ 30,000), and finite-thickness walls of variable conductivity, in the context of the design of liquid metal blankets for fusion reactors, as being attempted in the ITER consortium. © 2018 by the authors of the abstracts.
