摘要

对带有两种不同头部结构（基准型为方案1，头部加装外套环为方案2）的三旋流单头部燃烧室进行了研究，对有两种头部结构的燃烧室进行了流场和燃烧场的数值模拟，在相同的进口试验条件下，用燃气分析法和15点测温耙分别测量了两种头部的燃烧效率、出口冒烟数和出口温度场.结果表明：三旋流器的燃烧效率超过了99.7%，加装外套环后其流场、温度场分布均较基准型有所改善，回流区更加饱满，油气混合和燃油雾化效果增强，出口温度分布系数（OTDF）和出口冒烟数分别降低了36%和25%.

Abstract

Triple swirler combustor with two different dome structures was investigated. The reference type was case 1

and the dome for the installation of outer ring was case 2. Numerical simulation was conducted for the flow field and combustion field of the two combustors. The combustion efficiency

smoke emission and exit temperature distribution of the two designs were measured by gas analysis and thermocouple under the same experimental conditions. The results showed that the combustion efficiency of the triple swirler was more than 99.7%. The flow field and temperature field distributions of the combustor with an outer ring were improved compared with the reference type; besides

the recirculation zone was plumper

and the effects of fuel mixing with air and fuel atomization were increased

and the outlet temperature distribution factor (OTDF) and smoke emission decreased by 36% and 25% respectively.
