Liquid metal brushes for homopolar devices

Design predictions for liquid metal current collectors require a thorough knowledge of liquid metal flows in a narrow gap between a fixed surface and a moving surface, with a strong applied magnetic field and with a free surface beyond each moving end of the gap. The radial and axial velocities in the secondary flow are reduced by a strong axial or radial magnetic field. For a sufficiently strong field, the azimuthal momentum transport by the secondary flow can be neglected. This assumption reduces the problem for a primary azimuthal velocity to a fully developed magnetohydrodynamic (MHD) duct flow problem with a moving wall and two free surfaces.
