The metal flow conditions in the early stages of filling play key roles in controlling the quality of the casting. Inappropriate filling for the castings usually causes surface oxide films to be folded into the bulk liquid or broken because of the high kinematic energy of the liquid metal, resulting in so-called surface turbulence . At present, how casting quality is affected by such entrained oxide film defects through the filling behaviour, in particular the entrained oxide film distribution associated with liquid metal flow field in moulds, has not been clearly identified.This research aims to investigate the effect of liquid metal flow behaviour in filling processes on the final casting mechanical strength. In the study, both numerical and experimental approaches will be used. The ability to identify such effect would assist casting engineers to improve the casting process significantly, with consequent enhancement of the mechanical strength and reliability of castings.The incorporation of the oxide film tracking model into the Flow-3D package to model the oxide film entrainment in the filling processes in typical moulds of different geometry will be carried out. This model will be validated against results obtained with the Real Time X-ray radiographic visualisation and SEM sample analysis. The casting samples based on improved design filling systems will be analysed using mechanical strength test and SEM techniques. The research aims will be accomplished by a postgraduate researching for a PhD over the usual 3 year period on the modification of Flow-3D code and the related experiments.
