摘要/Abstract

摘要：保持单环腔主燃烧室的扩压器，外机匣最大直径尺寸以及喷口不变的前提下，将其火焰筒结构重新设计为并联式双环腔结构,设计了6种不同旋流器组合的双环腔结构燃烧室.采用相同的物理模型(包括湍流模型、辐射模型、喷雾模型及污染排放模型等)，对单、双环腔主燃烧室分别进行全流程的三维计算.给出了燃烧室的总压恢复系数、燃烧效率、燃烧室出口温度分布系数、污染排放指标等燃烧室性能参数.对比分析了单、双环腔燃烧室的计算结果.结果表明，双环腔燃烧室置换单环腔燃烧室是可行的，该研究可为大飞机低污染大法动机的设计提供技术支持.

Abstract: In order to change a Single Annular Combustor(SAC) into a Dual Annular Combustor(DAC),the authors kept the diffuser,outer case and atomize of the SAC unchanged,redesigned the combustor from a single annular structure into a dual annular structure，and designed six different structure DAC.Taking the same physical models(including the turbulence,radiation,spray and emission models),simulations of three dimensional two-phase reacting turbulent flow in both the SAC and DAC were developed in the Fluent Code.The total-pressure recovery coefficient,temperature distribution and exhaust emission levels were given.Finally,by comparing the simulation results,the feasibility of displacing the SAC into DAC structure was certified.
