RESUMO

In this work a numerical method, using finite difference equations , is proposed to study the solidification of metallic alloys under unidirectional (slabs) and radial (cylinders and spheres) heat flux. The method is able to predict the tortosity and permeability of the dendritic channels , which are important to study pore formation during solidification. The method is aplied to study different alloys and different metal/mold conditions
