The simulation results are shown in Fig.3 to Fig.5. Fig.3 describes the filling process of three different viscosity
models. From the Fig.3 we can see that the Newtonian type fluid leads to the jet flow across the cavity, i.e., the
material is jetting to the end of the cavity and then flowing back on itself. Defects will occur due to the splash of
the material. However, the cases of Carreau-Yasuda model and Power Cut-off model are significantly different
from the Newtonian fluid. The fluid flows much smoother and fills the cavity in sequence from the left to the right.
This is mainly because that the viscosity of the semi-solid material is much higher than the Newtonian fluid, thus
the material can fill the corner of the cavity. Furthermore, the jet flow phenomena will probably not happen at the
flow front.
