中文摘要:
      旋转爆轰作为一种新型增压燃烧技术,具有释热速度快、熵增小、可控性强等特点,可大幅改善发动机的推力性能和循 环效率,在世界范围内得到了广泛关注和高度重视。针对旋转爆轰发动机设计与应用中面临的诸多瓶颈问题,综述了液态燃料旋 转爆轰技术的最新研究进展,分别从试验与数值模拟角度梳理了液态燃料的爆燃转爆轰技术,介绍了气液两相旋转爆轰波的传播 特性、敏感影响因素及其调控方法,在此基础上,从起爆、爆轰多物理场组织以及先进测试等3方面展望了未来亟需解决的关键问 题和发展方向。在未来一段时间内,实现旋转爆轰波的有效形成、自持稳定传播以及多目标综合性能调控依然是旋转爆轰技术应 用于液态燃料发动机面临的重大问题。
英文摘要:
      As a kind of novel pressure gain combustion technology,rotating detonation has the characteristics of fast heat release, small entropy increase and strong controllability,which can greatly improve the thrust performance and cycle efficiency of engine. In recent years,rotating detonation has been widely concerned and highly valued in many countries. In response to the many bottleneck problems en? countered in the design and application of rotating detonation engines,this paper reviewed the recent research progresses of liquid-fueled rotating detonation technology. Specifically,this paper sorted out the research achievements of liquid-fueled deflagration-to-detonation technology and its typical enhancement methods in both experiments and numerical simulations. Besides,this paper also introduced the representative research results in gas-liquid two-phase rotating detonation wave propagation characteristics,sensitive influencing factors and its control methods. On this basis,this paper pointed out the key problems to be addressed urgently and the development directions from three important aspects including detonation initiation,detonation multiphasic organization and the advanced test. The present re? search shows that it will still be a major problem how to realize the effective formation,self-sustained stable propagation of the rotating deto? nation wave,and multi-objective comprehensive performance control in the future.
