Surface deformations of liquid metal flow in porous media in external uniform magnetic field

Direct numerical simulation of liquid metal flow in external uniform magnetic field was performed for the cases of three and six cells, which are assumed to be part of a porous material. Free-surface deformations were studied in terms of external magnetic field direction and strength, as well as, in terms of pressure drop, which was applied perpendicular to the direction of gravitation. Numerical results showed that magnetic field in the direction of pressure drop is the most effective to decrease the height difference between the inlet and outlet. In contrast, magnetic field direction perpendicular to pressure drop and gravitation produced the largest height difference.
