英文摘要	In the present paper, computational fluid dynamics (CFD) simulations were executed to exploring the intent of using aspirated cascade to replace tandem cascades. Firstly, the ONERA tandem cascades were investigated, and the performance of the cascades at the design point were listed, such as diffusion factor, total pressure loss coeffi- cient, deviation angle etc. For replacing the ONERA tandem cascades, a new cascade was designed with the codes BLADEGEN developed by the authors. The quasi 3-D calculations were carried out using the collection of programs for cascade analysis and design, MISES. The cascade was analyzed and designed by using this code. And the cascade was simulated and analyzed by commercial CFD software. It is found there is an obvious separa- tion on the suction side. Based on the 3D CFD simulation results of the cascade without aspiration, an aspirated cascade was designed by introducing a slot on the suction side. The performance of the aspirated cascade was in- vestigated and compared with the tandem cascades, indicated that under the same inlet condition, the total pres- sure loss of the single row aspirated cascade was less than that of the tandem cascades, and the outlet static pres- sure is higher than that of the tandem cascades. Meanwhile, the different suction slot location, suction width and suction mass flow are studied for the aspirated cascade.
