This paper shows that numerical analysis for thermal and fluid flow with phase change in casting, and the two-dimensional temperature distribution analysis by the infrared camera. Navier-Stokes and energy equation are solved simultaneously both for liquid and solid phase. The volume of fluid method is introduced into this numerical analysis. This method is performing interface movement using the rate of volume of the liquid which exists in inspection volume. Therefore, it is known that this method has the sufficient preservability of volume. In this study, the volume of fluid method is applied to the numerical analysis of the solidification process in the aluminum casting. As a result of performing numerical analysis, the temperature distribution and the solidification distribution are shown in this paper. Furthermore, thermal and fluid flow for solidification of the aluminum casting are visualized by using an infrared camera and a video camera.
