Numerical Simulation of Gas-Liquid Tow-Phase Flow During Complex Mold Filling Process

Abstract:

In order to predict defects of a complex casting that may arise during the die casting, The numerical analysis technique of Fluent' s VOF was used to establish the filling model. Based on the case of the wheel, it is expounded that the numerical simulation of VOF was utilized in application of casting. The five groups of simulation analysis were performed under the different pouring pressure. At last the pouring pressure has a great influence on the state of filling and the filling times are little difference. The research on pouring pressure and flow field during the casting process of wheels was conducted. The results of the study show that, when the pouring pressure is about 60000 KPa, the cavity is completely filled with the molten aluminum alloy.
