航空燃气轮机火焰筒高温低氧燃烧状态数值模拟

A numerical simulation of combustion status in air-turbine combustor tube of higher temperature air

高温空气燃烧技术作为一种全新的燃烧技术在国内外得到应用和发展,利用F luent软件对高温空气燃烧技术应用于某型航空发动机燃烧室进行数值模拟,并对数值模拟结果与传统燃烧技术进行分析对比。结果表明,该技术能够达到使火焰温度降低,出口温度场分布均匀,提高燃烧效率,节约燃料的综合效果。

The HTAC technology as a new combustion technology has been developed and applied at home and abroad. This paper utilized the advanced CFD code FLUENT to simulate air-turbine combustor flame tube using HTAC technology. By analysis and comparison of the simulation results with the traditional combustion technology simulation results. It is showed that the HTAC technology not only has decreased the flame temperature and has outlet eombustor temperature distribution uniformity, but also has the advantage of higher combustion efficiency and fuel saving.
