-solid slurry will involve a more complicated rheological behavior. So the mathematical model used in the numerical mould filling simulation of a liquid alloy cannot be used directly in that of the semi-solid slurry. That is to say, the mathematical model controlling the filling behavior of the semi-solid slurry must be used. At present, the constant or variable apparent viscosities about semi-solid......
