Numerical Investigation of Solitary Wave Interaction with a Row of Vertical Slotted Piles

Abstract

ABSTRACT Jiang, C.; Yao, Y.; Deng, Y., and Deng, B., 2015. Numerical investigation of solitary wave interaction with a row of vertical slotted piles. This study numerically investigated tsunami-like solitary waves propagating over a row of vertical, slotted, cylindrical piles. Existing studies using depth-integrated models, such as shallow-water equations, could not adequately resolve the wave dynamics over water depth. An alternative three-dimensional, numerical model, based on OpenFOAM® software, was developed for this study. The Navier-Stokes equations for two-phase, incompressible flow, combined with methods of large eddy simulation (LES) for turbulence closure and volume of fluid (VOF) for tracking the free surface, were solved. Laboratory experiments were performed on the measurements of flow near the piles and the dynamic pressures on the pile surface. The model was then validated with the laboratory data as well as data in the literature, and good agreements were found for wave, flow, and dynamic ...
