Magnetohydrodynamics Simulation of the Nonlinear Behavior of Single Rising Bubbles in Liquid Metals in the Presence of a Horizontal Magnetic Field

Rising bubbles in liquid metals the presence of magnetic fields is an important phenomenon many engineering processes. The nonlinear behavior terminal rise velocities as a function increasing field strength has been observed experimentally, but it remains poorly understood. We offer explanation through numerical calculations. A single rising bubble stagnant metal applied horizontal simulated. successfully reproduced; velocity increases with increase lower regions decreases higher regions. It shown that, region, average results from suppression fluctuations trajectory vertical plane perpendicular to field, consequence Lorentz force resulting component induced electric current due which (approximately) acts opposite direction that flow velocity. For strengths, induces broadened wake parallel decrease
