In this paper, we present the numerical study of interaction of a liquid metal flow with a small permanent magnet. Such an analysis is of fundamental interest for applications involving Lorentz Force Velocimetry (LFV). As a canonical problem, we consider the flow of liquid metal in the creeping flow regime (Re=0.01) through a square duct with electrically insulating walls. For this setup, we perform magnetohydrodynamic (MHD) simulations by coupling the commercial finite volume solver FLUENT and finite element solver COMSOL Multiphysics. Parametric analyses are performed at different relative positions of the permanent magnet with respect to the duct and with different magnetisation directions. The analyses provide good reference results for qualitative understanding of MHD flows exposed to non‐uniform magnetic fields. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
