dc.description.abstract | 本文利用CFD的計算軟體Fluent作為模擬的軟體,模擬風力發電機葉片翼型利用微凸結構改良後與翼型原型比較升阻力係數所產生的變化。本文對兩種不同的風力發電機葉片常用之翼型S809與Naca63-415做一完整的研究分析,並在葉片上設計加裝一微凸結構來判斷其對葉片運轉功率的改良效果,本文分別針對三種不同之位置及長度的微凸結構進行模擬分析,以判斷微凸結構之位置及長度對運轉效率的影響情形;此外,在流體黏滯性方面的考量,本文亦將數值分析模型以兩種不同雷諾數進行計算分析。本文利用套裝軟體Fluent將各種微凸結構設定情況下之葉片翼型的升、阻力係數做一模擬估算,並利用參考公式之數學理論求得該葉片翼型受風後之最大獲得功率;另外,本文亦比較原型翼型及加裝微凸結構後之翼型其兩者間功率變化的情況,以進一步分析、比較、判斷、評估微凸結構所能提升之葉片運轉效率,最後本研究亦歸納出微凸結構在各種情形下所達到有效提升功率的效果。 | zh_TW |
dc.description.abstract | This article uses Fluent’s Computational Fluid Dynamics software to simulate the comparison of lift and drag coefficient between airfoil with microtab and airfoil prototype. Two commonly used airfoil of wind turbine blade, S809 and Naca63-415, are analyzed in this study;the variables of microtab are location and length, which respectively are simulated under three different conditions. In addition, the changes of two different Reynolds numbers also are analyzed in the simulation. After simulating the lift and drag coefficient under each condition, the formula of airfoil maximum acquired power is then applied to compare the effect on the power variation of airfoil prototype with microtab. Moreover, comparison between the efficiency of increased power is implemented to further understand under which condition microtab can effectively increase power. | en |
