Solidification begins during pouring in casting processes, and the pouring rate influences the solidification pattern and soundness of products. In this research, the combined simulation of fluid flow and solidification 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 solidification, and the influence of pouring rate on the solidification pattern and shrinkage shape of pure Al casting was investigated. Solidification simulation and stabilized flow 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 influence 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.
