| 摘 要： | 给出了某型涡扇发动机的清洗方式、时机及清洗系统初始设计参数;利用流场仿真验证技术,对清洗系统进行了仿真验证和参数优选,结果表明:清洗液与空气的质量百分比不大于3%时,喷入清洗液不会影响风扇的稳定工作;300μm左右的液滴用于清洗综合效果较佳;在系统其他参数相当的情况下,喷嘴喷雾锥角越大,液滴对风扇进口的径向覆盖越好;无...

| Abstract: | An initial cleaning project was presented,including cleaning types,frequency and its design parameters for a turbofan engine.Using flow field simulation technique,the initial cleaning project was validated and its designing parameters were optimized.All these works show that:detergents injection will not affect this engine fan's stability at detergents-to-air ratios less than 3% by mass;the larger nozzle spraying angle means better droplets cover of the fan in the radial direction at equivalent other system... |
