摘要
通过全速势方程的数值积分，利用ＡＦ２格式，给出了一种用于叶轮机中叶栅型面的气动设计和绕流计算的便捷方法，对于稳态亚音速、跨音速及超音速流动均适用。与目前普及很广的、在超音区应用人工压缩性的方案相比，该算法有明显的优势。
convenient and speedy used for aeromechanic design and calculation of turbine cascade profiles, based on numerical integral to full potential equations and AF2 (Approximate Fatorization) procedure, is presented, which is applicable to steady subsonic, transonic and supersonic flows. Compared with the scheme using artificial compressibility in supersonic zone, which is very popular at present, this method shows its obvious superiorities.
