| 摘 要： | 采用雷诺应力模型(RSM)对于同旋向多旋流器阵列贫油直喷(LDI)燃烧室流场进行了数值模拟.计算结果表明,9个旋流器产生的回流区迅速变形衰减,在远离旋流器阵列的下游,形成了一个大的总体旋流.流场中存在的多个回流区及强湍流表明该燃烧室有潜力实现良好的燃烧性能.通过将RSM的模拟结果与激光多普勒测速仪(LDV)测量值进行比较发现,RSM准确描述了绝大部分流动特性,较好地求解了回流区和高速度梯度问题.

| Abstract: | The flowfield in a lean direct injection(LDI) combustor with co-rotating multi-swirler array was investigated using Reynolds stress model(RSM) computationally.The computational results indicate that the recirculation zones generated by nine swirlers deform and decay rapidly,and a unified and large swirling flow is formed far downstream of the swirler array.The existence of recirculation zones and strong turbulence levels indicate the potential for excellent combustion performance and low NOx emissions.The R... |
