Abstract
Quantitatively understanding the positions and magnitudes of fluid crash in the casting process is important for optimising the design of a pouring system. A three-dimensional theoretical model, coupled with a heat transfer and fluid flow model, is developed to simulate the fluid crash during the mould filling process. In this model, the velocity data resolved from the fluid flow simulation and the geometrical data calculated from the original stereolithography geometry are combined to determine the crash force. The implementation details of the model are also given. Practical simulation examples demonstrate that the present numerical model could be applicable to predicate the evolution history of the crashing force and possible damages of the mould surface in the mould filling process.
