As we know, inverse techniques make blade ' s profile well compatible with its surface velocity distribution, however, they give designers big challenges that the ideal velocity distribution is hard to obtained and sometimes the non - physical solution, such as double covering of flow field or unclosed profiles, would come out. the proposed design procedure in the paper has avoided the disadvantage mentioned above. in this paper, a quasi - irrotational equation is used to describe the flow in cascade instead of the generally used irrotational equation
眾所周知，一般的反問題和混合問題的最大特點，是在給定的壓力面和吸力面上的壓力分佈或速度分佈條件下，直接得到葉片的幾何形狀，它可以使葉型型面與表面氣流參數有機結起來；其不足之處在於，對設計者而言，很難給定理想的葉片表面壓力分佈或速度分佈，並且有時會得到一個非物理解，如：得出的初始葉型可能會出現前緣、尾緣不封閉的現象。 -
