Abstract
In this paper, we provide a hybrid incompressible Smoothed Particle Hydrodynamics (ISPH) model for fluid-structure interactions. The numerical algorithms include the mirroring treatment of solid boundary, free surface tracking, wave damping using sponge layer and fluid-solid coupling model. The proposed ISPH wave tank is applied to a series of wave-structure coupling problems including the sloshing in a baffled tank, solitary wave impact on an underwater obstacle, water entry of a cylinder and balance dynamics of a floating object. The simulation results demonstrate that the ISPH model provides an accurate simulation technique in various fluid-structure coupling studies.
