Title: Mathematical Modeling Of Solidification [modelagem Matemática Da Solidificação]
Author: Spim J.A.

Abstract: The structural integrity of shaped castings is closely related to their temperature-time evolution during solidification and the as-cast structure. A number of analytical and numerical models were developed in the last three decades to treat heat transfer during solidification, and the consequent simulation of freezing patterns in castings has provided many improvements in foundry processes. The use of casting solidification simulation could do much to increase the process knowledge. However, some uncertainties must be eliminated before such simulations can be widely accepted as realistic descriptions of processes such as: foundry, continuous casting of billets, blooms and slabs, strip casting, rapid solidification etc. The studies can be grouped in two categories: solidification in steady-state heat flow and in the unsteady-state regime. Reliable prediction in the latter category is of prime importance, since this class of heat flow regime encompasses the majority of industrial solidification processes.
