| Abstract: | The mold filling is one of key processes in material forming engineering. Many defects, such as air and inclusions entrapment, splash and so on, may occur if unsuitable mold filling is designed. The numerical simulation can simulate the real mold filling, and can provide insight into the flow patterns. The calculated results are important basis of the control of mold filling. Generally speaking, the mold filling with relatively high speed is turbulent fluid flow in most of cases, and anisotropic turbulen... |
