The numerical simulation of wave slamming on an open-piled structure using the SPH model

A two-dimensional numerical flume is presented to investigate the regular wave slamming on an open-piled structure using the corrected SPH method.The model employs CSPM and Riemann solution to discretize the Navier-Stokes equations.Solid boundaries are simulated by wall particles.The pressures of these dummy particles are determined by a coupling approach,which can keep the pressure field more stable near the boundaries.A new impacting boundary condition is proposed to track the hydrodynamic characteristics around the structure.The improved SPH model is employed to simulate the regular wave impacting the open-piled structure in the splash zone.The main features of the velocity and pressure fields near the structure are presented.And the model is validated against the experimental data and a good agreement is observed.
