| Outline of Final Research Achievements |
In this study, offshore floating vertical axis wind turbines(VAWT) supported at both ends as a new offshore wind power device is suggested. Initially, static simulations are carried out to characterize the behavior of the turbine blade considering rigid rotations with steps of 15deg by using Computational Fluid Dynamics(CFD) . It can be seen that the curve of the helical(60deg) blade is smoother than that of the Straight blade torque. In addition, the scale model which sets up both ends support vertical axis wind turbine to the floating body of the catamaran type is carried out windward flattery characteristics and the measurement of fluctuation response characteristic with wind-wave tank.
As a result, the suggested device in which direction of a wind turbine constantly and automatically faces toward a direction opposite to a windward. And we showed the possibility to decrease the heaving motion of the float of offshore wind power applied helical VAWT.
