摘要：
Adjoint method based design optimization is currently a hot topic in the field of fluid machinery, which has the advantage that the computation cost is almost independent of the number of design variables. In view of that few efforts in previous researches have been devoted to the inverse aerodynamic design of cascades with flow separation by means of the adjoint method, an optimization method for aerodynamic inverse problem of cascade, which includes blade geometry parameterization, grid generation, flow solving, adjoint field solving and optimizing, is proposed. From the point of view of weakening the flow separation, the aerodynamic inverse design of a cascade is completed by giving a desirable surface pressure distribution on the blade. The results show that the suction profile of the obtained blade becomes flatter than the initial design, and the flow separation near the trailing edge is weakened at two investigated attack angles. This approach is beneficial for the development of aerodynamic design technology of cascades with higher efficiency and wider operating range. © 2017, Editorial Office of Journal of Xi'an Jiaotong University.
