| Outline of Final Research Achievements |
In order to develop an efficient tool to analyze hydrodynamic and aerodynamic performance of a floating platform on which multiple wind turbines are installed, two numerical approaches, a CFD simulation method and a potential flow theory method, are studied. On the CFD method, an AMR (Adaptive Mesh Refinement) scheme is developed to increase the local resolution. The actuator line（ACL）method is implemented into the AMR code to solve the multiple wind turbine interactions. On the potential flow theory method, a new algorithm for numerical solution of the finite depth free-surface Green function in 3D is developed based on multiple series representations. A standard panel method and a Morison stick method have been developed and combined together to form a hybrid model to account for the viscous forces on the floating body with many slender trussed members. The BEMT model has been extended to treat the wind-lens and the wake effect.
