摘要

A constitutive model is developed experimentally for AI-7 percent Si-0.6 percent Mg alloy slurry. This equation has two parts to represent flow and structure evolution, The-model is then used to simulate filling of a chisel-shaped mold of cylindrical cross section. Transport equations are solved for the flow variables, and the free surface is modeled by solving the conservation equation for a scalar "fluid-marker" variable, which is used to update the fluid properties, including density and viscosity.
