Abstract:Additionally, the numerical model, upon which the sensitivity calculations are based, was verified against a turbulent filling experiment. The filling times and patterns for a simple mold were studied using water as an analog of liquid aluminum. Further, laminar filling experiments using solutions of glycerol and water were performed. As such, errors in the flow prediction could be attributed to either the VOF algorithm or the turbulent mixing length model. The results show good agreement between the macroscopic features of the VOF model predictions and those of the experiment. Also, the mixing length model was shown to be appropriate for the types of flows encountered in casting mold filling, and is able to capture the key features of the filling patterns.
