NUMERICAL INVESTIGATION OF WAVE INTERACTION WITH A GROUP OF PILES USING WCSPH METHOD

Cylindrical piles are commonly used in coastal and offshore engineering as support structures for piers, offshore platforms and wind turbines. Thus it is importantto understand the interaction of waves with a group of piles and to compute wave forces acting on the cylinders accurately. Weakly Compressible Smoothed ParticleHydrodynamic (WCSPH) method is a Lagrangian meshless method, introduced by Monaghan [1]. In this method, a computational domain is represented byparticles, which possess fluid properties. SPH method has been widely used for many applications such as modeling dam break, fluid-structure interaction, and solitary wave breaking.
