中文摘要 | 本文採用一混合方法來探討底部受定溫不同斷面環狀散熱片之暫態反應。方程式中之時間項以拉普拉斯轉換處理,使方程式變為邊界值問題,而空間項再以積分法處理。逆拉普拉斯轉換應用修正之傅立葉級數法。研究指出比爾特數和幾何參數對熱傳有相當影響。 |
英文摘要 | A hybrid method is used to investigate the transient response of annular fins of various shapes subjected to constant base temperatures. The time-dependent terms in the governing equations are removed by using the Laplace transform technique, and then the integral method is used to solve the transformed boundary value problem. The inverse Laplace transform is solved by utitizing the Fourier series technique with modifications. It is shown that the Biot number and geometrical parameters play an important role in the heat transfer. |
