dc.description.abstract | The coastal high way project E39 aims at building a continuous ferry-free road connection along the west coast of Norway. One of the major challenges in the project is to replace ferries with new fjord-crossing methods such as floating bridges and floating tunnels. The unique topographies of the Norwegian fjords pose deep water conditions and large scale wave transformations. This makes it more complicated to analyse the wave loads on the floating structures. In order to have a better knowledge of the wave height distribution, wave direction and wave transformation details, accurate simulations of wave propagations with good representations of the free surfaces are demanded. CFD (Computational Fluid Dynamics) is able to capture most complexities of the wave physics with few assumptions and has been widely and successfully applied on hydrodynamics. With increasing computational capacities, it is possible to use CFD on large scale simulations. Therefore, large scale three dimensional simulations of wave propagations into Sulafjord are performed in this paper with the CFD model REEF3D. The spectra wave model SWAN is used to obtain the wave data from off- shore data and give inputs for the CFD simulation. The CFD simulations are performed with both regular and irregular waves and give the details of the free surfaces and wave transformations in the fjord, the results of which are also compared with the wave model SWAN. REEF3D solves the incompressible Navier-Stokes equations with finite difference method and uses level-set method to capture the free surface under the two phase flow approximation. Together with the implements of high order schemes, REEF3D demonstrates high performance on wave hydrodynamics. The large scale Sulafjord simulation shows high resolution results and the details of wave transformations are well visualised. The results at wave probes are also compared between REEF3D and SWAN | nb_NO |
