Particle Simulation of the Transfer and the Pouring Processes of the Molten Metal

Abstract

  Particle-based computational methods, such as the Smoothed Particle Hydrodynamics (SPH) method, do not require numerical mesh. Because of the mesh-less characteristics, they are suitable for the numerical simulation including the free surface or moving boundary. In the casting process, molten metal is carried in a ladle and poured into the mold. Since there is a need to treat the moving boundary in order to simulate these phenomena, particle-based methods are suitable. However, there are only a few studies on the quantitative comparison between the computational results of particle-based simulation and experimental results and that evaluate the validity of the technique used. Thus we applied the smoothed particle hydrodynamics method to the transportation and pouring processes to validate the results with experimental data. We report the technique we used and the results obtained, which show good agreement with experimental data and our numerical results.
