Mitigation of Shock-Induced Separation Using Square-Shaped Micro-Serrations—A Preliminary Study

Fangyou Yu,
Zhanbiao Gao,
Qifan Zhang
et al.

Abstract: Suppressing shock-induced flow separation has been a long-standing problem in the design of supersonic vehicles. To reduce the structural and design complexity of control devices, a passive control technique based on micro-serrations is proposed and its controlling effects are preliminarily investigated under test conditions in which the Mach number is 2.5 and the ramp creating an incident shock is 15 deg. Meanwhile, a vorticity-based criterion for assessing separation scales is developed to resolve the inappl… Show more
