Abstract:

Hypersonic boundary layer transition plays an important role in the heat transfer, surface friction and flow separation of aircraft, especially in the reentry vehicle and air-breathing cruise aircraft. However, the cognition about boundary layer transition mechanism in present has been in a controversy. In this paper, the domestic research progresses of the hypersonic boundary layer transition are reviewed from the perspective of the evolution of disturbance wave, including receptivity, linear stability and nonlinear effects. In addition, the artificial transition technology based on harmonic resonance is taken for an example to demonstrate the application of transition mechanism with flow control. The generation and development of the disturbance is the core to recognize the boundary layer transition mechanism. So studying the disturbance wave from this aspect to develop the research application of innovation has significant influence to improve the vehicles' performance.

Key words: hypersonic, boundary layer transition, stability, disturbance wave, the second mode wave
