dc.description.abstract | 本文研究磁性流體電能轉換之實驗及理論方法於磁性流體通過線圈組之研究,並利用磁性流體感磁特性,改變磁性流體體積讓磁通量密度改變,以及利用感應電動勢(EMF)與速度呈線性關係,來改變速度與體積。在實驗中可以發現,磁通量密度只受體積影響,並不會受到速度干涉,而感應電動勢大小及方向則受磁通量密度及速度影響,當速度越大或磁通量密度越大時,感應電動勢會增大,在實驗中亦有觀察磁鐵及磁流體中兩者不同之處,磁鐵本身具有偶磁性,所以在磁通量密度表現上有兩個波峰,磁流體本身為順磁性,所以磁通量密度具有一波峰。資料處理方面利用快速傅立葉轉換方法將原始訊號處理,以有利於後續分析。將實驗資料整理一圖表,來觀察速度、體積與感應電動勢之三者關係,最後為了預測最大感應電動勢,本文首先提出單位體積修正因子( )加入法拉第感應電動勢方程式中,並且得到 ~0.006。 | zh_TW |
