Numerical simulation of incompressible flow with moving component using the MPS method

The moving particle semi-implicit (MPS) method is a fully Lagrangian meshless method developed for incompressible viscous flow. A particle interaction model of moving boundary was established for studying the flow with moving component. The simulation results of concentric shaft rotation were in good agreement with the analytic solution, and an example of cross agitator rotating in water was simulated, which well described the physic process. The new model expands the applications of MPS method and introduces a new way in studying on this kind of fluid machinery.
