燃烧室头部两相流场实验研究
Experimental Study of Two-Phase Flow Field in Combustor Head
-
摘要: 本文采用 PDA对燃烧室头部两相流动特性进行了研究,实验研究的模型燃烧室包括旋流器、喷嘴和火焰筒壁,保证气流结构与真实发动机燃烧室相似。实验对回流区内两相流场进行了细致的测量,给出粒子与气体速度分布。Abstract: Characteristics of Two-phase flow in combustor head have been researched experimentally with the help of Phase Doppler Analyzer.The distributions of mean velocity and fluctuating velocity,drop size and flux of spray have been measured.The detailed structure of spray in primary zone of combustor has been analysed.The results reveal the real flow field in the combustor head.
