CFD Modeling of Wave Loads on Offshore Wave Energy Devices

摘要

Numerical method based on a two fluid free surface capturing technique and Cartesian cut cell mesh is being developed for the simulation of wave loads on two generic classes of offshore wave energy devices under extreme wave conditions. To validate the code, a number of test cases including slamming and forced oscillation of axi-symmetric bodies near the free surface, dam break and its interaction with a small 3D box, wave generation in a 3D wave tank as well as wave interaction with a fixed wave power device have been calculated. Other test cases involving wave interaction with moving wave energy devices under realistic wave conditions will also be presented in the conference.
