Abstract

Computer modelling is an important tool for investigating manufacturing processes. This paper focuses on a numerical model of the Bridgman solidification casting process, used in applications where the solidification rate and temperature gradient require careful control. A 2D axisymmetric model for transient Bridgman solidification is presented. The governing heat equation is solved using a finite volume method where latent heat evolution is dealt with using the Scheil equation. The model is applied to Bridgman solidification of Al- 7wt%Si rods (of varying radii) for different values of Biot number.
