摘要
燃料的掺混增强技术是现代超燃冲压发动机的关键技术,针对如何使燃料充分掺混,研究人员发展了多种掺混增强方法,主要分为主动式和被动式两类。主动式掺混增强技术是依靠大尺度的自激励来提高燃料的掺混程度,因其易于控制、结构简单等优点逐渐受到研究人员的青睐。本文针对三种主动式掺混增强技术:等离子体能量沉积辅助掺混技术、波形/粗糙壁扰流技术和脉冲射流扰流技术进行了讨论,介绍了其研究现状和发展前景,并对未来的发展趋势进行了合理的展望,为未来超燃冲压发动机燃烧室内燃料掺混增强技术的进一步优化发展提供了思路。
Fuel mixing and enhancement is the key technology of modern scramjet engine.In view of the problem of how to fully mix fuel,researchers have developed a variety of mixing enhancement technologies,which are mainly divided into active and passive types.Active mixing enhancement technology relies on large-scale self-excitation to improve the mixing degree of fuel,and is gradually favored by researchers because of its advantages of easy control and simple structure.This paper focuses on three active mixing enhancement technologies:plasma energy deposition assisted mixing technology,waveform/rough wall disturbed flow technology and pulse jet turbulence technology,summarizes their research status and development prospect,and makes a reasonable prospect for the future development trend,which provides ideas for the further optimization and development of fuel mixing enhancement technology in the future scramjet combustor.
