摘要

提出了一种加力燃烧室新型中缝式稳定器.冷、热态试验研究表明中缝式稳定器具有结构简单、重量轻、低流阻、高燃烧效率、宽广的稳定工作范围等综合性能.利用PIV激光流场测试技术研究了中缝式稳定器尾迹流场

揭示其良好的燃烧性能取决于回流区结构和特殊的旋涡脱落方式.

Abstract

A new centrically slit flame holder(CSFH) for afterburner is presented

and the experimental research work shows that it has simpler structure

lighter weight

higher combustion efficiency

and better stability.The PIV technology was applied to study flow fields of the flame holder wake

which reveals that the good combustion characteristics depend on the recirculation zone structure of slit flame holder and the particular vortex shedding patterns.
