Abstract
The paper theoretically examines the solidification of a viscous and heat-conducting liquid metal filling in a cooling plane channel in a magnetic field. There is an electric current flowing through the metal. The metal flow is forced by constant pressure on the entry of the channel and by the Lorentz force. The differential equal of the liquid metal motion is obtained in the course of the conservation equations. The paper discusses the influence of the cooling conditions as well as the conditions of the flow on the solidification process. The dependence both of the dimensionless flow velocity and the dimensionless maximum flow distance on the cooling conditions are presented on the figures.
