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
