中文摘要: 本文以天然气同轴分级燃烧室为研究对象，采用FGM燃烧模型模拟研究了低工况下第一级燃油量对 燃烧室燃烧特性的影响规律。研究表明：中心级燃料量不变，增大第一级燃料量可有效增大甲烷燃烧面积， 同时燃料量增大到一定值时火焰面前端出现“M”型分布趋势;在中心级燃料退出后，燃烧产生的高温易将中 心级结构烧蚀，当燃料量继续增加，中心级燃料退出前后1 300 K等值线区域分布位置及形状均无明显差别， 在保证燃料当量比不变的情况下，中心级燃料退出与否对燃烧效率影响很小。
Abstract:In this paper，the natural gas coaxial staged combustion chamber is used as the research object，and the FGM combustion model is used to simulate the influence of the first stage fuel quantity on the flow field under low working conditions. Studies have shown that increasing the amount of fuel at the first stage can effectively increase the methane combustion area. At the same time，when the amount of fuel increases to a certain value，an “M”-shaped distribution trend appears at the front of the flame surface; fuel exits at the central stage later，the high temperature generated by the combustion will easily ablate the central-level structure. When the fuel
volume continues to increase，there is no significant difference in the distribution position and shape of the 1 300 Kcontour area before
and after the central-level fuel exits. Under the condition that the fuel equivalent ratio remains unchanged，Whether the central fuel is
withdrawn or not has little effect on combustion efficiency.
