Investigation of the coupled heat transfer, fluid flow and solute transport during the strip casting process

Abstract In the present investigation, the coupled heat transfer, fluid flow and solute transport problem for a strip casting process is considered. Different from the previous modeling of the solidification phenomena, the process considered in the present investigation is governed by the strong forced convection. Computations are performed for 0.6% carbon steel. In the investigation of the solute transport, both direct and inverse segregation phenomena are taken into account.
