The solidification behavior of molten core materials in flow channels is one of the major concerns for safety analysis of the liquid metal cooled reactors. In order to analyze its fundamental behavior, a 3D fluid dynamics code was developed using a particle-based method, known as the finite volume particle (FVP) method. Governing equations that determine the fluid movement and phase change process are solved by discretizing their gradient and Laplacian terms with the moving particles and calculated through interaction with its neighboring particles. A series of molten-metal solidification experiments using a low-melting point alloy was performed to validate the developed 3D code. A comparison between the results of simulations and experiments demonstrates that the present 3D code based on the FVP method can successfully reproduce the observed solidification process.
