Abstract:	本研究探討正方形孔穴於不同傾斜角度下，具波形熱壁面時之自然對流分析。採用Galerkin高階微分法處理可壓縮Navier-Stokes統御方程式，並將流通量分解成對流項、擴散項以及壓力項，其中壓力項分開計算在於近壁面以非中央之外插方式計算之。加總之各點流通量利用預置矩陣以二階Runge-Kutta時間積分方式疊代。數值分析之正確性可利用文獻結果驗證。文章透過流線、等溫線、局部紐塞數以及平均紐塞數方式探討瑞利數105下自然對流之現象，至於在傾角變化其範圍在0o-180o，波形壁之波數範圍在0-3，波形壁之波 A numerical study of natural convection inside an inclined cavity with a hot wavy wall was carried out. This problem is solved by using a high order Galerkin discretization scheme for the steady compressible Navier-Stokes equations. The pointwise numerica
