Abstract: The paper presents transient distributions of physical fields, computed with LES (Large Eddy Simulation), for turbulent bubbles flow through electrically conductive liquid in rectangle bubble reactor (RBR) or cylindrical bubble reactor (CBR), which are placed in external uniform horizontal or vertical magnetic field. Experimentally verified (without magnetic field) Euler-Euler approach, realized with ANSYS Fluent Magnetohydrodynamic (MHD) module, is used for multiphase flow, when continuous phase is electrically conductive liquid (water-like liquid or Wood-metal) and dispersed phase is gas (air or nitrogen) bubbles.

Keywords: Numerical simulation, bubble reactor, multiphase MHD-flow, Euler-Euler approach, LES, uniform magnetic field
