A Study of Wind Power System with Twisted Vertical Axis Blades on Trucks

[[abstract]]本研究旨在建構車用扭曲式垂直軸葉片之風力發電系統。目前全球的燃油車輛正面臨石化燃料日益短缺的危機，且交通運輸排放CO2對環境也造成了負面的衝擊，所以在交通工具上開發替代能源的使用有其必要性。本研究以「回收風能再利用」的觀點，研製車用風力發電系統，透過資料分析法作為設計上之參考，並以TRIZ理論與風力機空氣動力學理論設計垂直軸葉片之外型與尺寸，進而整合傳動裝置、發電機、充電控制器實現車輛在移動中，可將風能轉換為電能儲存作利用。本研究使用ANSYS CFX計算流體力學軟體分析各個模擬情況的車流場與風力機之動態情形；在實驗測試中，車用風力發電系統安裝於車頂前可達300Watts的發電量，且由模擬結果驗證安裝位置在卡車車頂前方是系統發電效率最佳之位置。[[abstract]]The aim of this study is to construct the wind power system with twisted vertical axis blades on trucks Nowadays the shortage of fossil fuels consuming on vehicles are in an emergent situation Moreover the CO2 emissions from transportations make a strong negatively impact on our environment Therefore it is necessary to develop the renewed energy for transportations This study adopts the viewpoint of recycled wind energy to develop a wind power system on vehicles The designed model was based on the method of documentation as a support TRIZ theory and the theory of wind turbine aerodynamics Then an integration of a gearing the generator and a charge controller were carried out in a moving vehicle which could convert the wind power into electrical energy for storing and utilizing This study adopts the CFD simulation software of ANSYS CFX to analyze the flow field of a trunk and the dynamic status of the wind turbine in different situations of simulations The result shows that the wind power system of vehicles could achieve the generating capacity of 300 Watts Besides the result from the simulation as evidence to support the most appropriate installation position is the front roof of the truck which could achieve the better electrical efficiency in this researc
