Description
Summary:碩士 === 國立屏東科技大學 === 機械工程系所 === 100 === Starting is very difficult in the traditional horizontal axis wind turbine , because Horizontal axis wind turbine is suitable for rated wind speed, In order to retrieve higher wind, but blade angle is too large in the stationary with wind direction, leading to the stall is not suitable for start. The purpose of this paper design of a leading blade for the easy starting of a HAWT. The parameters of the auxiliary blade twist angle, wingspan long chord length adjustment and use HAWT design to computational fluid dynamics method, The commercial software Gambit is used to generate the mesh system required, and Fluent is used to solve the flow field , Join the auxiliary blade followed by added compared to the start up to 30% of the torque increase conditions, operating conditions, the wind coefficient decreased by 40%
