800K 做比較,比較模擬的結果可看出,與 Tian, W. & Yang, R. [29]所做的數據仍 然有段差距,尤其在線型複合材料方面,數據差異性蠻大的,由於本文所採取的 界面穿透率算法是以Chen,1998 [4]所提出的穿透率算法為主,與 Yang 等人所採 用的 Dames,2004 [10]所提出的算法不同,且在界面條件的設定上,可能還有問 題存在,才會導致結果數據相差甚多,雖然BTE 的計算與 MC 本身就會有誤差 存在,但相差超過10%,當中應該還有問題尚未解決。

未來展望:

本文目前只採用一階隱式迎風算則作計算模擬,在準確度方面當然也會有點 差,且在線型的模擬方面,格點測試收斂性還是欠佳仍需要再修改,在未來後續 之研究能夠繼續修改程式的完整度且能夠採用更高階的算則來計算,以提高精準 度。

由於 Yang 等人已經有利用直接蒙地卡羅(DSMC)模擬出三維的現象,在本文 研究中,由於未使用平行運算,且三維的計算量過於龐大,必須仰賴平行運算才 能夠計算得出結果,期待未來後續的研究能夠將往三維的方向進行,能夠將問題 從一維探討到三維結果,將這一系列的問題做更完善的探討。
