Abstract

The finite difference method and the VOF method have been used to develop a three dimensional numerical model to study wave interaction with a perforated caisson. And the partial cell method is also adopted to this type of problems for the first time. The validity of the present model, with and without the presence of structures, is examined by comparing the model results with experimental data. Then, the numerical model is used to investigate the effects of various wave and structure parameters on the wave forces and the wave runup of the perforated quasi-ellipse caisson. Compared with the solid quasi-ellipse caisson, the wave force of the perforated quasi-ellipse caisson is significantly reduced with the increasing of porosity on the perforated quasi-ellipse caisson. Furthermore, the perforated quasi-ellipse caisson can reduce the wave runup compared with the solid quasi-ellipse caisson. This reduction tends to increase as the porosity of the perforated quasi-ellipse caisson and relative wave height increase.
