Abstract:	本文主要探討穿音速微小擾動方程式邊界值問題,並利用相似轉換法,求出穿音速(微超音速M/sub .inf./.gtoreq.1)流經凸角之扇形膨脹波流場及凹角楔形面之壓縮波流場相似解,並計算出其斜震波之位置與表面壓力係數, 經與完整斜震關係式所得之精確解比較,而獲得滿意之結果。應用凹角及凸角之相似解,可解析地求出穿音速流經雙楔形翼剖面邊界值問題之流場解,及翼前、翼後緣震波之形狀、位置、及各項氣動力係數,以提供數值計算之參考。 The similarity solution to the boundary value problem of transonic centered expansion and compression waves is given. In particular, its application to finding the analytical solution of the double wedge airfoil with leading and trailing shock is exhibited. The similarity solution is used to check the accuracy in the numerical results.
