Solidi cation begins during pouring in casting processes, and the pouring rate in uences the solidi cation pattern and soundness of products. In this research, the combined simulation of uid ow and solidi cation simulation was performed based on the MPS method (a particle method) to analyze the behavior of shrinkage formation from the beginning of pouring to the end of solidi cation, and the in uence of pouring rate on the solidi cation pattern and shrinkage shape of pure Al casting was investigated. Solidi cation simulation and stabilized ow simulation programs based on the particle method were combined considering the temperature-dependency of density. The proposed method was applied to shrinkage formation analysis based on the in uence of pouring velocity on the shrinkage formation behavior. The results showed that the depth and shape of shrinkage agreed well with corresponding experimental results. The shrinkage formation behavior could also be directly calculated.
