  The computer simulation of inclusion motion and final trapped position in casting was carried out in this study. The sand casting of aluminium is taken as an example of numerical analysis, and the simulation is carried out for various foundry conditions. In the simulation, inclusion movement after cavity filling, residual flow and trap stituation of inclusion during solidification are analyzed. The location of inclusion particles trapped in the solidified phase changes widely with inclusion density, size, particle inflow time and inflow position. In particular, the density difference between inclusion and molten metal has significant effects on the particle trapped place in cast metal. Based on the information on detailed motion, place of inclusion entrapment and its mechanisms in varions casting conditions as given in this study, the optimum casting conditions can be designed in order to reduce inclusion defects.
