Numerical simulation of three-dimensional fluid flow and heat transfer in electromagnetic steel casting

Abstract

This paper aims to present a mathematical model and numerical technique to study the three-dimensional fluid flow and heat transfer in the electromagnetic steel casting process. The effect of source current density on the electromagnetic force as well as on the flow and temperature fields is investigated. The numerical results indicate that the source current density of different magnitudes have a considerable effect on the flow field of molten steel and a higher source current generates a lower speed of molten steel near the mould wall. Consequently, the recirculation zone moves further away from the mould wall, and the speed of molten steel decreases while the heat transfer rate increases significantly. © 2009 Academic Publications.
