近年來,綠能意識崛起。小風機有著在低風速下能有效利用、易安裝、便宜和美化建築等等的優點,成為來多種小型發電機熱門之ㄧ。本研究借用蜻蜓優越的空氣動力學特性故選定蜻蜓翅膀為仿效對象,採用其翼面的剖面為參考翼型,再予以簡化後成為平版頗翼加上有皺褶的佈局,利用商業軟體(ICEM CFD)建立幾何體與網格,其後透過計算流體力學(CFD)商業軟體ANSYS FLUENT 進行模擬改變不同形狀之參數得到較佳扭矩大小以做最為近一步改良依據。本模擬首先以本體平板厚度為依據模擬量測,將不同厚度之葉片在相同功角下進行模擬,選擇較佳扭矩力之葉片厚度。以同樣模擬模式改變前緣長度、皺折型態、皺折數目、以及皺軸高度與翼弦長度比作為基本設計參數進行模擬。每當改變一參數得到較佳解後,將延用其參數特色至下個參數模擬,最終得到最佳蜻蜓翅膀翼型剖面做為葉片設計,並對不同設計參數得到之效應進行探討與分析。
This project imitates dragonfly’s superior aerodynamic characteristics to the turbine blade, to refer to wing cross section to a flat plate by adding corrugated characteristic .The software ICEM CFD was used to simulate flow field with different shapes of parameters to the models to get better torque. It reveals that dragonfly’s corrugated wind can be a strong inspiration on designing micro wind turbine wind turbine blades.
