A numerical approach based on a lattice-Boltzmann model of two-phase flows has been developed to investigate the characteristics of bubble flow in an electroconducting liquid in a vertical channel under the action of an external magnetic field. Bubble driven flows have found wide applications in industrial technologies, such as mixing of metals and hydrogen production. To control the bubble motion in two-phase flows, e.g., in gas-liquid metal, the external magnetic field due to magneto hydrodynamics effects is used. The first results in a two-dimensional approach show that the magnetic field has a remarkable impact on the motion of the liquid. Figs 4, Refs 16.
