【 摘 要 】

COMFLOW is a general 3D free-surface flow solver. The main objective in this paper is to extend the solver with apermeable flow model to simulate wave interaction with rubble-mound breakwaters. The extended Navier-Stokesequations for permeable flow are presented and we show the discretization of these equations as they are implemented inCOMFLOW. An analytical solution for the reflection coefficient of a permeable structure is derived and the numericalmodel is compared to the solution. In addition, a validation study has been performed, in which we compare the numericalresults with an experiment. In the experiment, pressures and surface elevations are measured inside a permeable structure.The measurements are represented well by the simulation results. At the end, a 3D application of the model is shown.
