To study the specialties of wave slamming on horizontal plate structures and beam-plate structures,we establish two-dimensional regular wave numerical models based on software FLUENT.Adopting RANS equations and standard k-ε equations and using the VOF method,we reconstruct the free surface.Through typical cases of wave slamming on panel structures are reproduced,and the models are verified by experimental data.Then with plentiful simulation the impact pressure distribution rules during slamming are obtained.The statistical distribution data are analyzed and the fitting formula of distribution width is put forward,which may serve as reference for the engineering design.
