Abstract

Modelling combined heat transfer, convection, solidification and stress deformation in castings K. Pericleous, M. Cross, P. Chow & C. Bailey Centre for Numerical Modelling and Process Analysis, University of Greenwich, London ABSTRACT The team at CNMPA has developed a unified approach for the modelling of all the macroscopic physical phenomena that take place in the casting of metals. This approach combines Control Volume (CV) numerical techniques with Finite Element (FE) mesh structures. It is incorporated in a new three- dimensional CFD code called PHYSICA [1] and its two- dimensional variant UIFS [2] and has also been embedded in the proprietary code ASTEC [3] . It has been applied to a number of casting problems to predict mould filling, solidification, thermal stress induced distortion and the creation of voids. The method is described in this paper, together with example applications. INTRODUCTION The casting of metals combines several physica
