In this research, we carried out a numerical simulation of stirred fluid by rotating gear using MPS method. MPS (Moving Particle Semi-implicit) method is one of the mesh-free particle methods. The particle method has used an effective technique to treat a free surface flow such as dam breaking or splash. Usually, the particle methods use particles for structure expression as well as fluid, but we used a polygon model on the boundary to improve the accuracy of interaction between fluid particle and structure surface. As a result, we could make a prediction of stirring-resistance value in good agreement with experimental measurement, and yielded a stress distribution by viscous fluid on the polygon surface.
