Numerical Simulation of Flow and Heat Transfer during Filling Process Based on SPH Method

Abstract:

Expected to the non-grid characteristics and pure Lagrangian properties of SPH, the simulation of casting’s filling process would be simpler and precise. In this study, the implementations of SPH method are studied for liquid metal flow and heat transfer during the filling process. The temperature based thermophysical parameters are fitted and add into flow-heat coupling program. The temperature recovery method is included to consider the effect of latent heat. The validation of one-directional heat transfer problem shows that the SPH results have good agreement with the analytical results. The maximum relative error is less than 3%. Finally a circular part is calculated and proved that the SPH model used here works well and has enough precision to capture the behavior of the filling process.
