中文摘要 | 當今可再生能源發展正方興未艾,但風能產業的技術已逐漸趨於成熟,然而風機的能源轉換率仍屬偏低,只有約貝茲極限的75%。本文主旨在探討自風能中多次擷取能量的可行性,作法是在風機的下游端設立另一組葉片,以提升風機的效率。但瞭解到上游端的葉片會產生紊流層,阻礙提升效率的目的,所以本文提出了給下游端葉片組的安全區。此外本文也指出對毗鄰的垂直軸式風機,彼此以相反方向旋轉方式運行,能減少相互間的干擾,可產生良好的結果。 |
英文摘要 | While the renewable energy becomes popular, the technology of wind turbines is gradually getting mature. Nevertheless, the power coefficient is still low, at only 75% of the Betz limit. This article explores the possibilities of multiple extractions from wind to boost its efficiency by constructing a second set of the blades at the downwind side of the turbine. In realizing the wake of the first set of the blades may hamper its purpose, a suitable zone for the second set of the blades is provided. Another discussion is also brought up of using counter-rotating VAWTs may provide an overwhelming outcome. |
