Numerical simulation of transport phenomena in solidification of multicomponent ingot using a continuum model

A continuum model proposed for dendrite solidification of multicomponent al loys, with any partial solid back diffusion, was used to numerically simula te the macroscopic solidification transport phenomena and macrosegregations in an upwards directionally solidified plain carbon steel ingot. The compu tational results of each macroscopic field of the physical variables involv ed in the solidification process at a middle solidification stage were pres ented.
