The flow behavior of solid-liquid two phase flow during mold filling effects greatly on the properties of castings such as semi-solid metal products and particle-reinforced metal matrix composites. In this study, the flow behavior of solid-liquid mixture flowing into a rectangular cavity with a core was investigated using a water-polystyrene particle mixture. The shape of the free surface of the mixture in the cavity with a core was more stable than without. Even a small core of 2mm×2mm was effective. The main reason for the phenomena is the change in the flow path of the mixture due to the core. Although gas was entrapped near the core, the amount of the gas was less for the core with the same width as the gate than the cavity without the core. The low-concentration region of solid particles appeared at the V-shaped flow boundary, which existed upward from the bottom of the core. The concentration of particles decreased at the center of the rotation of flow, which existed under, at the side of, and above the core.
