Abstract: In order to study the?high?temperature?rise?combustor，the designed high temperature rise multi-swirl combustor，center-staged combustor，as well as the existing single annular combustor(SAC，designed fuel/air ratio is 0.027)，were analyzed with numerical simulation method. For the condition of design state where fuel/air ratio is 0.037，it is demonstrated that multi-swirl and center-staged device could both reach the ideal combustion criteria，with pattern factors (OTDF) reaching 0.138 and 0.16，respectively，which could both meet the high temperature rise combustor requirements. However，the SAC combustion performance is sharply deteriorated，which can not reach the requirement. Center-staged combustor technology advantages are quite obvious，indicating its prospects as high temperature rise and high capacity combustor，while multi-swirl combustor has the advantage of high temperature rise as well as low emission.

摘要： 为了研究高温升燃烧室，采用数值研究的方法，对所设计的高温升多级旋流燃烧室和中心分级燃烧室与现有的单环腔燃烧室(SAC，原设计油气比为0.027)在设计油气比0.037条件下进行分析。研究结果表明:多旋流和中心分级的设计方案均可获得理想的燃烧性能参数，出口温度分布系数(OTDF)分别达到0.138和0.16，满足高温升燃烧室的设计指标，而SAC燃烧性能急剧恶化，不能满足设计指标。其中，中心分级燃烧室的技术优势十分明显，显示出作为高温升高热容燃烧室的发展前景；多旋流燃烧室则兼具高温升和低排放两方面优势。
