Magneto-hydrodynamics of multi-phase flows in heterogeneous systems with large property gradients

Abstract The complex interplay between thermal, hydrodynamic, and electromagnetic, forces governs the evolution of multi-phase systems in high technology applications, such as advanced manufacturing and fusion power plant operation. In this work, a new formulation of the time dependent magnetic indu...
