摘要
激波/湍流边界层干扰(STBLI)是航空航天领域中广泛存在的一种复杂流动现象,形成条件涵盖跨声速到高超声速,形成环境复杂多样,给飞行器的气动性能和结构安全性带来重大的影响。结合STBLI的典型流动图像介绍了干扰区的重要物理特征;总结了一些有代表性的STBLI流动控制技术的现状,分析了包括涡流发生器、电磁激励等控制技术的原理、效果及不足;探讨了STBLI流动控制研究中有待于进一步深入研究的问题和方向,为发展实用、高效、针对高超声速条件下的STBLI流动控制技术提供了理论支撑和技术储备。
Shock wave/Turbulent Boundary Layer Interaction(STBLI)is ubiquitous presence in aircraft engineering.Occurring in the case from transonic to hypersonic,the complex linear and nonlinear mechanisms in the STBLI such as the flow separation,peak heating and low frequency pressure fluctuating can heavily affect the vehicle,inlet and component geometry,structural integrity,material selection,fatigue life and the design of thermal protection systems.Therefore,the flow control is considered as a key issue to adjust the flow field of STBLI.To deepen the understanding of STBLI and its flow control,the present paper conducted a comprehensive review on the important knowledge,mostly the flow control techniques such as vortex generator,plasma and magnetohydrodynamics for STBLI to improve the flow control design and troubleshooting of STBLI in engineering,especially in the case of hypersonic.
