The Moving Particle Semi-implicit (MPS) method is one kind of particle method, which is based on Lagrangian approach. It has been developed to analyze complex thermal-hydraulic problems, including those in nuclear engineering. Since meshes are no longer used, large deformation of free surfaces or interfaces can be simulated without the problems of mesh distortion. This approach is effective in solving multiphase fluid dynamics which is subject to complex motion of free surfaces or interfaces. Since its development, MPS method has been extensively utilized for a wide range of applications in nuclear engineering. In this chapter, the basic theory of the MPS method is explained firstly. After that, some examples of its application in nuclear engineering, including bubble dynamic, vapor explosion, jet breakup, multiphase flow instability, in-vessel phenomenon, molten spreading, molten core concrete interaction and flooding, are presented.
