在目前全球能源危機與環保議題日益嚴重的背景下，尋找與開發可再生能源越來越重要，而風能作為其中的一種，具有豐富的潛力與未來。本研究是針對舊有的垂直Savonius式風機設計一新型的被動式導流板，希望以此提升其效能。在論文中將會詳細的講解設計理念以及機構設計概要，並透過電腦輔助工程(CAE)分析及機械設計相關經驗，發現機構中的設計缺失並提出一系列相關設計方案來解決機構缺陷，再藉由實際的測試來驗證方案的可行性。最終經由這些設計方案所開發出之被動式導流板，將轉速大幅提升，實驗結果表明，與未加裝本研究所開發的被動式導流板相比，轉速提升幅度達31%。這項研究透過創新的設計和分析，成功提高了垂直軸Savonius風力發電機的效能，為未來風能技術的發展提供了新的可能與方向。

Amid the mounting global energy crisis and environmental issues, the exploration and development of renewable energy sources are of increasing importance. Wind energy, as one of these sources, holds tremendous potential and prospects. This study aims to design a novel passive deflector for the existing vertical Savonius wind turbines to enhance their performance. The paper will delve into the design concept and outline of the mechanism, and through Computer-Aided Engineering (CAE) analysis and mechanical design experience, it will identify design flaws within the mechanism. Following this, a series of relevant design solutions will be proposed to rectify these defects, and their feasibility will be validated through actual testing. Ultimately, the passive deflector developed through these design solutions successfully elevated the rotational speed significantly. Experimental results indicated that, compared to the case without the installation of the passive deflector developed in this study, the increase in rotational speed reached 31%. Through innovative design and empirical analysis, this research has successfully enhanced the performance of vertical axis Savonius wind turbines, providing new possibilities and directions for the future development of wind energy technology.
