Notes:
Techniques of numerical simulation on mold filling process of casting are investigated inthis paper. The mathematical model is formed on the ground of some selected theories incomputational fluid dynamics (CFD), Numerical Heat Transfer (NHT) and computational methodsto interfacial tracking. The discrete solution to the governing equations appeals to Finite VolumeMethod (FVM) on structured mesh. As for viscous turbulence flow and multiphase fluid flow inmold filling, engineering turbulence model and Volume of Fluid (VOF) method are adopted in thealgorithms, respectively. As a debut, the general-purpose CFD software is used to establish thepracticable mechanical model for the simulation. By means of numerical simulation, variation anddistribution of velocity, temperature, stress and configuration of casting, etc. with respect to timeand space in the filling process can be quantitatively analysed in detail, which is helpful forengineers to optimize their design of technics with less time and less cost and is meaningful toprovide the subsequent simulation, solidification process of casting, with initial conditions
