Fluid-rigid body interaction simulation based on a stabilized ISPH method incorporated with the impulse-based rigid body dynamics

Research output: Contribution to journalArticle

Abstract

In fluid-rigid body interaction simulation based on the particle method, incompressible Smoothed Particle Hydrodynamic (ISPH) method is used to resolve the problem of fluid particles’ motion and impact load on the structure in the meanwhile DEM based on the penalty method is commonly applied to deal with the contact problem of rigid bodies. However, the accuracy of penalty method relies on a relatively small time increment. In this paper, the impulse-based rigid body dynamics is applied to deal with the collision contact problem instead of the conventional penalty method for robust and faster computation.
