| Abstract: | Total pressure pulsation intensity and eddy scale, which are the primary parameters used for describing the pulsation intensity and the size of the distorted flow field, affect the stall margin of engine greatly. It would be useful in the research of engine stability control by realizing the change trend in the distorted flow field and their relationship. Consequently, the change trend of the total pressure pulsation intensity and eddy scale in accordance of the growing up of the inflow was discussed, and finally, the relationship of them was also revealed. |
