摘要：
In order to have a detailed understanding of distortion effects on intermediate duct, a set of evaluation parameters for intermediate duct were proposed, and research of distortion effect based on these parameters was conducted on a small turbofan intermediate duct to study the mechanism of distortion development. The results showed that with the expansion of inlet distortion range, distortion of the outlet is gradually weakened compared with the inlet, in some cases the distortion can be reduced. Compared with inlet flow, outlet low total pressure area of casing shrinks, and outlet low total pressure area of hub expands. While the inlet low total pressure area of casing expands, the outlet distortion near hub will be strengthen. While the inlet low total pressure area of hub expands, the outlet distortion near the hub will be weaken. © 2021, Editorial Department of Journal of Propulsion Technology. All right reserved.
