摘要：

In this paper, Smoothed Particle Hydrodynamics (SPH) was used for the prediction of heat conduction problems in sand cast process. The implementation of solidification modeling in a curved casting based on SPH has been described. The treatment of latent heat was introduced in SPH conduction problem by temperature compensation method, which demonstrated the role of latent heat has a great influence on the heat distribution in the casting. The temperature distribution calculated by SPH provided a great agreement with those computed through numerical software MSC.Marc, which validated the efficiency and precision of SPH simulation of heat transfer problems in sand cast process.
