航空煤油转子发动机缸内流动特性和燃烧特性研究
Study on Flow and Combustion Characteristics in-cylinder of Aviation Kerosene Rotary Engine
转子发动机是一种具有潜力的无人机动力设备,RP-3航空煤油是我军燃料通用化研究的重点研究对象。为此,开展航空煤油转子机的研究具有十分重要的科学意义。本文以Z160风冷转子机为研究对象,基于流体动力学仿真平台,建立并验证了转子机仿真计算模型。研究了转子机分别燃用汽油和航空煤油时,缸内流场分布、火焰传播过程、缸内压力变化等燃烧特性以及污染物质量变化。研究结果表明:(1)由于转子发动机特殊的旋转运动方式和燃烧室结构,缸内充量的流动非常复杂。(2)由于航…查看全部>>
