A Finite-Volume Model for Numerical Solidification of Mg Alloys

Article Preview

Abstract:

Solidification of a wedge casting of magnesium alloy AZ31 in the presence of melt convection is investigated. The formulation used in the in-house code is developed based on the finite-volume method on unstructured grids and utilizes a colocated finite-volume framework. In the discretization of the mass and momentum equations all novelties proposed in [1] are implemented and a source based-energy equation is presented. The volume fraction of solid in the domain and the cooling rates at six different embedded thermocouples are predicted. These results are compared to previous experimental work and against similar results obtained with a widely used commercial software package.
