中文摘要 | 本文利用有限元素正交適位法(the method of orthogonal collocation on finite elements)推導批式吸附器之近似解,結果顯示,對大範圍之分配比值(partition ratio)及/或Biot數時,若分割元素的交界位置隨吸附時間而改變,則只須分割成兩個元素且每一分割元素只需使用一個內部適位點,便可得到比以前文獻提出之近似法好很多的準確度(相對誤差都在2%以內)。 |
英文摘要 | A new approximate method derived from the technique of orthogonal collocation on finite elements with moving junction was much better than the other methods proposed in the past. With one point collocation on each subdomain, the relative error was less than 2% throughout the time domain for wide ranges of partition ratio and Bio number. |
