摘　　要：超声速条件下燃料与空气的高效掺混是实现超燃冲压发动机燃烧室高效燃烧的基本前提。然而受到流动压缩效应和燃烧释热的影响,超声速流动的混合过程受到了极大的抑制。涡流发生器是目前研究最多、应用最为广泛的混合增强技术之一,按照几何构型的不同可将其分为波瓣混合器、斜坡喷注器以及微型涡流发生器等。本文按照先介绍结构和机理,再介绍研究进展的顺序对波瓣混合器、斜坡喷注器以及微型涡流发生器在超声速混合增强领域的应用进行了综述。之后对涡流发生器和其他激励组合式混合增强技术,如涡流发生器-斜激波诱导混合增强,等离子体式、振荡式涡流发生器等进行了介绍和技术展望,指出其可实现未来超声速来流条件下宽速域、动态时的高效混合。Efficient mixing of fuel and air under supersonic conditions is important for achieving efficient combustion in scramjet and combined-cycle combustion chambers.However,due to the effects of flow compression and heat release from combustion,the mixing process in supersonic flows is greatly inhibited.Vortex generators are currently the most researched and widely applied technology for mixing enhancement.According to geometric configurations,vortex generators can be categorized into lobed mixers,ramp injectors,and micro-vortex generators.In this paper,the application of lobed mixers,ramp injectors,and micro vortex generators in the field of supersonic mixing enhancement is reviewed in the order of introducing the structure and mechanism,and then introducing the research progress.Subsequently,vortex generators and other combination excitation mixing enhancement technologies,such as vortex generator-ramp induced mixing enhancement,plasma-based,and oscillating vortex generators,are introduced,and their technical prospects are pointed out,indicating their potential to achieve efficient mixing across a wide range of speeds and dynamic conditions in supersonic inflow.
