摘　　要：结合国内液氧/煤油发动机的研究,针对2种外环管切向进液流、内管进气流的同轴旋流式喷嘴,以酒精和压缩空气为工质,进行了喷雾流常压燃烧实验研究。使用红外热像仪测量了常压条件下喷雾流燃烧的温度分布,分析了火焰结构,定性研究了喷嘴形式和工况对燃烧性能的影响。At present,the researches on coaxial nozzle are almost developed surrounding hydrogen/oxygen engine.The researches on liquid oxygen/kerosene using kerosene/rich-oxygen gas nozzle are less reported.For two kinds of gas/liquid coaxial swirling nozzle,using alcohol and compressed air as working substance,the temperature distributions of burning spray flow under normal pressure were researched and the influence of nozzle type and working condition on the combustion performance was qualitatively analyzed.
