中文摘要：

应用三维数值模拟方法,研究了应用先进旋涡燃烧室(AVC)概念设计的燃烧室流动和燃烧特性.研究结果表明:AVC的总压损失系数、燃烧效率、旋涡结构和燃烧稳定性以及污染物排放,受前后钝体形成的凹腔结构内的气流喷射位置、喷射角度和主气流当量比的影响,其中受凹腔结构内的气流喷射位置影响最大.

英文摘要：

In this paper,numerical simulation was carried out to study the mechanism of stabilitating flame and reduce the polutant exhaust and the influences of the major parameters on combustion stability,combustion efficiency and emissins of advanced vortex combustor(AVC).The flow resistance,trapped vortex configuration and stability,combustion efficiency of AVC were influenced by the position,angle and equivalence ratio of airflow jet in the cavity between fore-body and after-body.The position of airflow jet in th...
