| 摘 要： | 采用雷诺应力模型（RSTM）对于两种多漩流器阵列结构的非反应流场进行了数值研究。在两种结构中一种为同旋向漩流器阵列,另一种为反旋向漩流器阵列,每种结构均按3×3阵列排布。计算结果表明,两种结构产生的流场十分复杂,同旋向漩流器结构中九个漩流器产生的回流区迅速变形衰减,在远离漩流器阵列的下游,形成了一个大的总体漩流;而在反旋向漩流器中各回流区维持了较长的长度。两种结构流场中存在的多个回流区及强湍流表明燃烧室有潜力实现良好的燃烧性能。通过将RSTM计算结果与激光多普勒测速仪（LDV）测量值进行比较发现,RSTM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 non-reacting fluid flow fields generated by multi-swirler arrays with two different configurations were investigated using Reynolds Stress Turbulence Model(RSTM) computationally.These two cases include a co-swirling array and a counter-swirling array,and each configuration consists of a three by three arrangement of swirlers.The computational results indicate that the flow fields considered here are of very complicated structures in both cases.In comparison,in the co-swirler configuration the recirculat... |
