COMPUTATIONAL FLUID DYNAMICS ANALYSIS ON WIND TURBINE ROTOR WHICH CAN OPERATE AS BOTH HORIZONTAL AND VERTICAL AXIS TYPES

抄録

A novel wind turbine that can operate as both horizontal axis wind turbine (HAWT) and vertical axis wind turbine (VAWT) is under development. The wind turbine (D=750mm) utilizes the exhaust flow from a cooling tower in order to generate electricity. In this study, the power performances as both types were calculated by computational fluid dynamics (CFD). The effects of the shape of a nose cone on the performance were also investigated in the case of HAWT mode. A small brim at the edge of the nose cone did not give significant effects on the rotor power performance.
