Computer simulation of mold filling and solidification has significantly impacted the casting industry by reducing scrap rate and improving soundness. However, experimental data are needed for simulation verification. In the past, model substances and X-ray film recordings were employed. Since actual mold filling is much faster than that can be captured in detail with conventional video equipment, this work uses a higher frame rate. The results of a high speed video camera study are presented for the filling of a vertical mold with cast iron. Details of the dynamic filling are compared with simulation results. The influence of filters on mold filling will be assessed and use of this technique to select filter coefficients for computer simulations will be discussed.
