摘　　要：对装有 3个双旋流气动雾化喷嘴的矩形燃烧室试件 ,在头部流场测出的情况下 ,用燃气分析技术对燃油分布进行实验研究。实验结果表明 ,在回流区以及两个喷嘴之间的区域局部油气比很高但燃油质量流量低 ;而在主流区内的局部油气比接近恰当比但燃油质量流量高。This paper describes the fuel distribution of the primary zone in a rectangular testing combustor that has been fitted with three counter double\|swirler airblast atomizer. The investigation was made by the use of gas analysis technique after the measurement of the flow field. The results of fuel distribution experiment indicated that the local fuel\|air ratio is very high and fuel mass\|flow is low in the recirculation zone and the region between the two atomizers, but the local fuel\|air ratio is close to the proper value and the fuel mass\|flow is high in the main stream. These experimental results are important in the research of that type of engine.
