Abstract

Abstract

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.
