摘　　要：应用Fluent软件,研究平焰煤气燃烧器形成旋转射流方法和机理,采用标准k-ε模型对平焰燃烧器三维流场进行数值模拟。通过比较,数值计算结果与理论规律符合较好。可直观地显示平展气流的形成过程以及流速、压力和湍流的分布规律,为煤气平焰燃烧器的设计、研究提供了有效的研究方法和途径。用标准k-ε模型来预测旋转射流具有较高的准确性,通过数值模拟,可代替大量的实验探索,在很大程度上,缩小实验范围,节省人力物力,是一种经济有效的研究手段。The computational fluid dynamics is used to study the swirling jet of flat flame burner, and the standard k-ε model of the fluent soft is used to simulate the three-dimensional flow of fiat-flow combustion. Compared with the experimental data, the result of calculation well accords with the experimental data. It reveals the process of formation of fiat flame and the distribution of the velocity, the pressure and the turbulence clearly. This supplies a reference and a warrant for the study and the improvement of the fiat flame burner. The result shows , adopting the standard k-ε model to predict the swirling injection is correct. It is an economical and effective means instead of the experimental research.
