Abstract: Convection of electrically conducting fluids such as liquid metals in the presence of
magnetic field is a major area of investigation, e.g., crystal growth processes. The usage
of a magnetic field is known to inhibit the thermal flow in the liquidus phase, and it is
utilized in the design phase of casting systems. This study is concerned with the heat
transfer and flow in electro-conductive melts in solidification systems. A mathematical
model of the underlying physical processes is established, and numerical simulation
results obtained by a home-made code, based on the finite differences HSMAC scheme,
are reported: second order central finite differences for the viscous terms, third order
upwind (UTOPIA) finite differences for the convective terms, and first order forward
finite differences for the time derivative.
