This paper presents a numerical study to enhance the mixing of polyurethane resin in a container. In general, the properties of polyurethane resin vary with the production environment, such as temperature. However in this study we assumed that the dynamic viscosity of the polyurethane is kept constant at 15 [Paㆍs]. We computed the flow solution and visualized the mixing pattern for different shapes of mixers by using commercial code, ANSYS CFX. In order to quantify mixing, we employed the concept of mixing index by volume integration.
