Direct Numerical Simulation of Wave Overtopping of Upright Seawall with Permeable Wave Chamber in Irregular Wave Field
2008
There are mainly two ways to compute wave overtopping phenomena. One of them is a numerical method which employsa non-linear wave transformation equation combined with an overtopping formula. Another is a direct numericalmethod for solving Navier-Stokes equation. Only a few numerical studies with the direct numerical method have so farbeen made on irregular wave overtopping. In the present study, the applicability of the CADMAS-SURF, which is basedon the VOF method, for the numerical simulation of irregular wave overtopping of an upright seawall has been verifiedby comparison with the hydraulic model experiments. Moreover, some consideration for calculating irregular waves hasbeen shown.
