Abstract:	本論文之研究為建立一分析超音速可壓縮流之噴流流場。在數值方法的選擇上，採取可壓縮流領域中的加權型基本不震盪算則直接求解Navier-Stokes 方程式。而程式撰寫技巧上採用具增強數值穩定性的 Lower-upper Symmetric successive over relaxation ( LU-SSOR method ) 以增強數值之穩定性及加速程式之收斂。文中包含了平板噴流的渦漩運動的特性及紊流超音速混合層的特性，其結果顯示都有不錯的精確度。 The basic idea of this research is to establish a numerical simulation,which analyzes the effect of compressibility of supersonic jet flow phenomena. The numerical simulation method adopted is the "WENO" schem developed for compressible flow solving the N
