| Wave overtopping simulations over coastal structures
Jong-Chun Park
The Journal of Mechanical Science and Technology, vol. 22, no. 6, pp.1222-1229, 2008
Abstract : A large-eddy simulation (LES) model has been developed to investigate nonlinear wave run-up and overtopping.
The Navier-Stokes equations are solved by using a finite differential algorithm, and the modified Marker-Density
Function (MDF) technique (Miyata and Park, 1995) is employed for solving nonlinear free-surface motions. In order to
evaluate the present model, three numerical simulations are presented: solitary wave run-up on a vertical wall, flow
over a broad-crested weir, and regular waves overtopping a sloping seawall. The results are compared with data from
experiments and other numerical models.
