Abstract
Metallographic and fractographic studies of aluminum casting show that oxides are frequently observed in the neighborhood of porosity defects. It has been proposed that the entrapped oxides in the collision of melt surface during mold filling become nucleation sites of porosity. In this work, we proposed a new method that can simulate oxides entrapment during mold-filling process, and final size and distribution of the oxides after the mold filling. In this model, the oxides are represented by marker particles and the velocity of markers is calculated in a similar way to the Marker and Cell method. It was found that this algorithm can predict the distribution of porosity that could not be predicted by conventional methods.
