| Abstract: | The low pressure casting process of a box was simulated using ANSYS software based on the computational fluid dynamics(CFD) and the computational heat and mass transfer theory.The flow field in the low pressure casting filling process of aluminum alloy,and the temperature distribution and solid fraction distribution in the solidification process were analyzed.Furthermore,defects that may appear in the castings were predicted that will help to optimize the casting parameters and die design. |
