• 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
  众所周知，一般的反问题和混合问题的最大特点，是在给定的压力面和吸力面上的压力分布或速度分布条件下，直接得到叶片的几何形状，它可以使叶型型面与表面气流参数有机结起来；其不足之处在于，对设计者而言，很难给定理想的叶片表面压力分布或速度分布，并且有时会得到一个非物理解，如：得出的初始叶型可能会出现前缘、尾缘不封闭的现象。
