Abstract

Liquid metal flow behavior under magnetic field and electric current is investigated in experiment and numerical simulations. Several aspects of the resulted Lorentz force action are discussed and demonstrated. The enhanced flow mixing induced by the non-uniform current density appears to be crucial for the heat transfer efficiency. Also the outflow heat flux is strongly affected by the action of the \JxB force.
