摘要：
In this work, our computational fluid dynamics (CFD) solver naoe-FOAM-SJTU is adopted to simulate the interaction between focused waves and a moored hemispherical-bottomed buoy. This solver adopts a two-phase Navier-Stokes model and a spring mooring system. Three crest-focused wave groups, based on NewWave theory, are generated and validated against the experimental measurements from the Collaborative Computational Project in Wave-Structure Interaction (CCP-WSI) working group. Numerical results for the buoy's heave and surge displacement, pitch angle, and mooring load are compared against corresponding physical data. The effects of wave steepness on the behavior and mooring loads are discussed.
