Numerical investigation of seabed response under waves with free-surface water flow

Research output: Contribution to journalArticle

Abstract

Seabed response caused by waves is investigated numerically with a 3-dimensional coupled solver of fluid flow and consolidation. The free surface is modeled by the Volume of Fluid (VOF) method, and the water wave is generated by the numerical wave maker boundary condition. An iterative numerical scheme is proposed to solve the Biot consolidation equation using the finite volume method (FVM). The coupling between water wave and seabed is through stress and continuity condition on common boundaries. The numerical test shows good agreement with the analytical solution. A 3-D application of seabed response under waves with the presence of the object is also carried out. The current model can also be used at the onset of piping scour.
