Abstract:

Shock wave and its interaction are widespread flow phenomena in the internal and external flow of supersonic/hypersonic vehicles, and will cause serious problems such as increased drag, increased pressure load and thermal load, and low-frequency unsteady oscillation, seriously affecting the range, structural life, and flight safety of the vehicles. As a new way to solve the above problems, active flow control technology has attracted extensive attention in recent years, and is expected to become a new degree of freedom in future vehicle design. The recent progress of active flow control technologies applied to shock wave control, shock/shock interaction control and shock wave/boundary layer interaction control is reviewed, with emphasis on the control effect and mechanism of active flow control technologies such as active jet, laser energy deposition and plasma discharge. Finally, the weaknesses of the current active flow control methods for shock wave and its interaction are discussed and corresponding prospects are made.

Key words: shock wave, shock/shock interaction, shock wave/boundary layer interaction, active flow control, active jet, laser energy deposition, plasma discharge
