教育用低風速小型風車之開發
The Development of The Educational Small Wind Turbine for Low Wind Velocity
摘要
隨著1973年爆發石油危機，人類才開始重視能源的問題，並著手於尋找各種替代能源，風能是近幾年世界各國研究替代能源中的重點領域。風車的性能好壞影響截取風能的效率的高低，且風車的性能好壞除了環境的因素外，主要取決於風車翼片、翼型、與角度…等因素。本研究從事，小型風車的設計與改良、翼片的製作與封裝、實驗設備的建立與量測等，共歷時兩年。 本研究目標在於設計製作一台教育用小型的水平式矩形直線翼風車。矩形直線翼葉片的翼型採用Clark-Y 、Naca0012、L3012，三種不同的翼型，分別針對2、3、4、5翼等不同的翼片數的配置，與-5°、-10°、-15°的裝置角進行實驗研究，嘗試建立今後設計小型教育用風車的設計資料與原則。

Along with the Cold War broke out in 1973, until today human has started to pay much more attention on the problem of the sources of energy, and sets about looking for all kinds of alternative energy resources. And wind power is the key field in alternative energy resources study. Yet windmill capabilities often deeply influence the efficiency to intercept the energy of wind, and in addition to environment factors, windmill capabilities depend mainly on the blades, the airfoil and the angles of blades. From small-scale windmill designing and improving, blades manufacturing and packaging, to equipment founding and measuring, the process of this research has been lasting for two years. The targets of this research are: designing and producing an educational small-scale rectangular horizontal bladed wind turbine; developing small-scale horizontal windmill system; trying to apply three kinds of straight rectangular airfoils, Clark-Y﹑Naca0012 and L3012, to windmills; experimenting and recording how can the number of blades, ranging from two to five blades, when matching up with the gradient of -5°﹑-10°﹑-15° affects the capabilities of windmill.
