Modelling of the investment casting process

The aim of this paper is to present the modelling work carried for the FOCAST project in order to acquire a better understanding of the physical phenomena which control the investment casting processes. The paper will first present the general approach used by the authors. Then, for each process stage studied, the models used and their hypotheses are presented and discussed. The parameters needed for the modelling are also listed. From these models, and using simulation packages, numerical simulations have been carried out. The results obtained are presented, with a special focus on the comparison with experimental results where available.
