摘    要:通过三维计算流体动力学(CFD)数值计算,研究了加力燃烧室中三种不同型式的锯齿冠状混合器及环形混合器的掺混性能.结果表明:①锯齿冠状混合器下游形成了流向涡阵列,锯齿布置和倾角对其尺度和强度有较大的影响;②相邻锯齿交错布置的锯齿冠混合器的强化掺混效果最为显著且流动损失相对较低,总压恢复系数相对环形混合器降低在0.2%以内...

关 键 词:齿冠状混合器  加力燃烧室  掺混  数值计算  混合特性

Abstract:Three-dimensional computational fluid dynamics(CFD) computations were conducted to analyze the mixing characteristics of three types of chevron mixers and the confluent mixer used in the afterburner.The research results obtained in the present conditions show that:(1) an array of stream-wise vorticity could be induced by chevron mixers,and the stream-wise vorticity scale and intensity are affected seriously by the chevrons arrangement and inclined angle;(2) the chevron mixer with chevrons tilted alternately...
Keywords:chevron mixer  afterburner  mixing  numerical computation  mixing characteristics
