Numerical Simulation of Rheological Behavior in Melting Metal Using Finite Volume Particle Method

Abstract

Particle methods such as the Smoothed Particle Hydrodynamics (SPH) method are computational methods that do not require a numerical mesh. As such, they are suitable for the numerical simulation of the semi-solid casting process, which is a kind of casting process. However, there are few precedent that the semi-solid casting was calculated by the particle method. We have developed the computational model of the shrinkage, the surface tension and the heat transfer. These are important elements to represent the semi-solid casting process. We show numerical results of the casting process by our method.
