一、前言 本试验研究是在文献[1、2]的基础上,对几种不同结构形式的涡流控制扩压器匹配相同火焰筒的扇形试验件所进行的试验,探求扩压器形式对燃烧性能的影响。同时也研究了抽气比、抽气方式及进口流场对燃烧效率、出口径向温度及壁温的影响。试图为该种扩压器的实际应用筛选更合适的结构方案,进而补充国内、外对该种扩压器研究工作中的不足之处。
I. Preface The experimental study is based on the literature [1,2], on several different forms of eddy current control diffuser fan test match the same flame test carried out to explore the diffuser form of combustion The impact of performance. At the same time, the effects of suction ratio, suction mode and inlet flow field on combustion efficiency, outlet radial temperature and wall temperature were also studied. Attempts to screen more suitable structure schemes for the practical application of this kind of diffuser will supplement domestic and foreign deficiencies in the research of this kind of diffuser.
