Abstract

Numerical computations were carried out for the mixed convection of liquid metal in a Czochralski configuration under an axial magnetic field. A crystal rod was rotated and a crucible static. For a static crucible, an application of an axial magnetic field yielded a rotation of a fluid column under a crystal rod. This was due to complicated effects of a Lorentz force. 1 Introduction The flow of electro-conducting fluid under an external magnetic field generates electric currents in the fluid and interacts with the external magnetic field to generate the Lorentz force. It is generally explained in text books e.g. Ref. f 1] that the Lorentz force acts to suppress the convection
