摘要/Abstract

摘要： 本文对双股同轴中心旋流突扩燃烧室进行了热态试验.在较宽的α变化范围内,得到了高的燃烧效率,同时伴随着一定的压力损失.中心回流区嵌套的流场结构,有助于产生较高的燃烧效率.

关键词: 突扩型燃烧室;燃烧效率;高温试验

Abstract: In this paper the experiment on the coaxial dump combustor with inner swirl inlet under the combustion condition was carried out. The high combustion efficiency was obtained within a wide range of a,and accompanied with low pressure loss.The embedded structure of recirculation zones is available to improve the combustion efficiency.

Key words: Dump combustion chamber;Combustion efficiency;High-tempera-ture test
