潜堤上波浪传播过程数值研究
Numerical Investigation of Wave Propagation over a Submerged Dike
摘要
Abstract
In this study,a computational model is established for solving wave propagation over a submerged dike based on RANS equations combined with Level-Set method.The fifth-order finite difference WENO scheme is used for spatial discretization,and a TVD third-order Runge-Kutta explicit time scheme is employed for time discretization in the model.The Level-Set method is used for tracking the free interface between the air and water phases,and a relaxation method is employed for wave generation and absorption.In order to validate the accuracy and applicability of the model,numerical investigation of the wave propagation over a submerged dike is conducted.The numerical results show a good agreement with experimental data.Further studies are carried out to investigate the influence of physical parameters,such as wave height,submerged depth,seaward and leeward slope gradients,on the process of wave propagation over a submerged dike.Results reveal that when the wave height is higher,submerged depth smaller,and seaward slope flatter,the effect of shoaling is more obvious;when leeward slope is flatter,the effect of shoaling on wave is slightly larger,but not obvious.关键词
