Abstract

This paper focused on the development of Computational Fluid Dynamics (CFD) by a mathematical model based on the control volume method, which would enable efficient simulation of the semi-solid processing of complex industrial casting parts. Theoretical basis of the numerical simulation was briefly introduced. The latent heat was incorporated using the effective specific heat. The mass, momentum and enthalpy transport equation for each phase were solved. The application of the model allowed determining the temperature fields in the metal and the mold at 1 sec and the liquid fraction at time step 0.15 s with three different pressure regimes. The calculated pressure distribution and the evolution of liquid fraction through the material were examined and used to clarify their influence further investigated with tensile and hardness testing.
