Abstract

Abstract: In order to investigate the effects of multi-factors，including mass flow rate，combustor geometry(swirler geometry and mixing zone geometry)，pre-heating temperature and fuel composition，on combustion induced vortex breakdown (CIVB) flashback，Design of Experiments (DOE) method was adopted for parametric analysis. For the simulation of CIVB flashback，two-dimensional axisymmetric model was used implementing user defined function (UDF) to represent the function of swirler. Through analyzing the results，the successive order of factors affecting CIVB flashback is swirler geometry，mixing zone geometry，preheating temperature，fuel composition and mass flow rate. Wherein，the first four factors have highly significant effects on CIVB flashback. By contrast，mass flow rate and the interaction between any two factors have insignificant and negligible effects. By further investigating，it is found that all the parameters take effect on CIVB flashback through changing flow distribution and flame properties.

摘要： 为了能够全面考察多因素，包括质量流量、燃烧室结构(旋流器结构和预混段结构)、温度和燃料组分等对燃烧诱导涡破碎(CIVB)回火的影响，采用试验设计(DOE)方法进行多参数数值分析。对于CIVB回火的模拟采用二维轴对称模型，并补充用户自定义函数(UDF)来模拟旋流器的存在。结果表明:因素对CIVB回火影响的重要程度排序依次为:旋流器结构>预混段结构>温度>燃料组分>质量流量；其中，旋流器结构、预混段结构、温度和燃料组分对于CIVB回火具有高度显著的影响，而质量流量以及任意两因素间的交互作用可以忽略；各因素主要通过改变流场和火焰特性作用于CIVB回火。
