摘要
本文在低速风洞中，利用在线式互相关ＰＩＶ系统，对尾缘吹气式火焰稳定器及Ｖ型火焰稳定器的近尾迹流动进行了测量，分析了瞬态场尾流结构，表明了可控横向射流与主流的相互作用形成可变回流区的特点及其与钝体回流区在流场结构上的不同，为揭示气动稳定器的稳焰机理及燃烧性能的进一步研究提供了重要的理论依据。
The detailed near-wake flow behind the Edge Blowing Mixture Curtain (EBMC) flameholder and V-gutter flameholder were investigated by using 2D cross- correlation on-line PIV in a low speed wind tunnel. The instataneous wake structure was analyzed, the characteristics of the variable recirculation zone formed by the interaction of the jet and the main flow and its difference with the flow structure of V-Gutter flameholder were revealed. All of these offer important theoretic basis for revealing the flame stability mechanism of jet flameholder and further studying its combustion performance.
