摘要：

Hydrodynamics characteristics of land hinged Oscillating Wave Surge Converter (OWSC) are investigated by smoothed particle hydrodynamics (SPH). delta-SPH model is used to remove the spurious high-frequency oscillations. Boundary force model is used to avoid the penetration of fluid particles across the wall. The classic equations of rigid body dynamics are used to control the motions of OWSC. Standing waves, regular waves, the interaction between wave and rigid plate and bottom hinged OWSC are simulated to validate the numerical methods. Comparing SPH results with the analytical solutions or reference results, relative good agreements are observed. Then, SPH method is employed to simulate interactions between waves and land hinged OWSC. The results show that the active power of land hinged OWSC strongly depends on both the PTO damping coefficients and the wave periods.
