Abstract:	波形壁流場在工程與科學領域上有相當重要的應用與重要的地位。亦可應用於熱傳導方面，波形壁有助於表面積的增加，可利加快散熱速度。再者亦可發展溝槽薄膜，法國空中巴士A320 試驗機將其貼覆於飛機70%表面達到節省1~2%之燃料之功效。因此針對該特性進行超音速流場與次音速流場之數值模擬研究，在數值方法的選擇上，以加權型基本不震盪算則 (Weighted Essentially Non-Oscillatory)直接求解奈維爾-史托克(Navier-Stokes)方程式。而程式撰寫技巧上採用Lower-upp The flows over a wavy wall play quite important roles in engineering and scientific applications. Since wavy wall can increase boundary’s surface and speed up radiation, therefore wavy wall flows can be applied in the area of heat conduction. Moreover a c
