    • 本文所探討的系統為流體流過一塊表面具有多孔隙之平板，其板面可噴出或吸入相同的流體。並且同時考慮固體壁中的熱傳導及流體的熱對流對系統的影響，兩者合併求解。這種必須同時考慮固體內熱傳導與流體熱對流的複合系統，稱為共軛（conjugate）熱傳系統。
    本文對以下兩個熱傳系統，進行理論解析與數值模擬：
    一、噴流或吸流（blowing and suction）對平板系統的傳導與強制對流之共軛熱傳的影響。
    二、噴流或吸流對垂直板中的傳導與自然對流之共軛熱傳的影響。
    無噴流或吸流，以及平板外壁表面維持等溫或等熱通量的加熱方式，都是本文所涵蓋的特例。
    所得數值結果顯示：噴流效應使邊界層厚度增加，因而使等溫板系統之熱傳速率減少，或使等熱通量板之板面溫度增高；吸流之效應則恰巧相反。
