摘要/Abstract

摘要：从发动机燃烧性能的角度出发，研究了航空发动机改地面燃机后燃用其他燃料对燃烧室性能的影响.利用流体计算软件Fluent，针对地面燃机燃烧室燃用航空煤油、轻柴油、工业酒精、天然气4种不同燃料，进行模拟计算，给出燃用不同燃料时的燃烧性能.结果表明，从燃烧的角度来看，轻柴油的燃烧性能与航空煤油差别不大，可直接替代航空煤油或与航空煤油混合使用,燃用天然气的NOx排放及CO排放都很低，天然气是一种理想的低污染燃料.工业酒精由于物性及热值与航空煤油差距很大，地面燃机改烧工业酒精还需作相当深入的研究.该研究对发展下一代航空替代燃料有一定的参考价值.

Abstract: From the angle of engine combustion performance,the influence of the alternative fuel on combustion performance after the aeroengine changed into floor combustion gas turbine was researched.FLUENT,fluid computing software,was used to compute different alternative fuels on the combustion properties.For the floor combustion gas turbine combustor in the burning of aviation kerosene,light diesel oil,industrial fuel alcohol and natural gas,simulation was carried out,and the engine combustion performance of different fuels was given.The result showed that,from the angle of engine combustion performance,there was no difference between aviation kerosene and light diesel oil,which can be used directly or combined with aviation kerosene by engine combustor.The emission of NOx and CO from natural gas combustion was 1 000;natural gas is an ided low-emission fuel.There was a wide gulf between the aviation kerosene and the industrial fuel alcohol,which needs an in-depth study for the technology on changing fuel from aviation kerosene to industrial fuel alcohol after the aeroengine changed into floor combustion gas turbine.The research has a valuable reference for the development of the next generation of aviation alternative fuel.
