中文摘要 | 本文利用偶積分方程式法(coupled integral equation approach)及結合梯形 法則( trapezoida rule )與兩點赫米近似法( two-point Hermite approximations ) ,應用在二維矩形平板散熱片暫態熱傳問題中,可得修飾一維矩形平板散熱片暫態熱傳方程 式,仍具有傳統一維方程式之簡單式。結果顯示,修飾一維方法的溫度分佈與根部熱通量均 比傳統一維方法較精確。 |
英文摘要 | This work utilize the coupled integral equation approach, the simple trapezoidal rule and the two-point Hermite approximations for this two-dimensional prblem. A modified one-dimensional transient heat transfer equation is obtained which keeps the same simple form as the 1-D equation. Results show that the accuracy on average temperature profiles along the fin and heat flux at the base in the modified 1-D analytical solution is better than classical 1-D approach. |
