SPH Simulations of Regular and Irregular Waves and their Comparison with Experimental Data

Abstract

This paper presents the Smoothed particle hydrodynamics (SPH) model to examine the propagation of a regular and irregular waves. The SPH method is a grid-less Lagrangian approach which is capable of good accuracy in tracking large deformations of a free surface. The computations are validated against the experimental data and a good agreement is observed. The SPH modelling is shown to provide a promising tool in predicting the transformation of different waves.
