Numerical Study of Co-Axial Pilot and Main Module Combustor

针对新一代高温升燃烧室燃烧组织问题,提出了一种满足高温升燃烧室要求的方案,设计了先进的发散小孔冷却结构和同心圆式主副模分区的头部燃烧组织,采用稳态的压力求解器结合非预混PDF模型,对慢车和设计两个工况进行数值研究。通过数值计算获得了燃烧室速度场和温度场分布特性,结果显示了良好的分区供油分区燃烧组织特性。

For combustion organization problems of the new high temperature rise combustor, a scheme including advanced effusion cooling structure and co-axial pilot and main module dome burning organization is designed. By solving the N-S equa- tions, combined with non-premixed of PDF model, the computation is performed for the idle and design condition. The veloci- ty and temperature field characteristics are obtained by numerical study, and the results show good partition burning organiza- tional characteristics.
