摘要：
In order to further explore the mechanism of unsteady pulsed suction (UPS) to control flow separations in a highly loaded compressor cascade and investigate the adaptability and flexibility of UPS under different incidence angles, the effects of UPS on flow field performances under different incidence angles are studied systemically by numerical simulation, and the comparative analysis between UPS and conventional steady contant suction (SCS) is carried out. The results show that the control effect of flow separations for UPS under the designed incidence angle is obviously better than that for SCS with the same time-averaged suction flow rate. UPS shows better performances in a given range of excitation frequency with the time-averaged suction flow rate ms=0.4%, based on the optimum excitation frequency for UPS, the loss is reduced by 9.4% and the static pressure rise coefficient increased by 12.9%, and compared to SCS, the loss is reduced by 4.2% and the static pressure rise coefficient increased by 4.7%. UPS has still a greater advantage compared to SCS in a given range of excitation frequency under different incidence angles, however, the control effects of UPS and SCS are decreased under a large incidence angle. © 2019, Editorial Department of Journal of Propulsion Technology.
