CFD Analysis of Water Ring Arising about Floating Rotor of Offshore Wind Power Plant

摘要

Paper describes CFD calculations of water flow about floating rotor forrnnew large-scale vertical axis wind turbine supported by pontoon withrncolumns (WEMU type). The research goals are to verify flow mode, torncalculate a hydrodynamic power loss, to find out an influence of waves.rnWater ring arises about the pontoon during rotation. Power loss isrnproportional to second power of rotational velocity. The ring can driftrnto outside because of water acceleration and aside due to waves.
