摘    要:为了评估雷诺数对某大涵道比涡扇发动机的影响,利用Wassell等修正方法,对发动机主要部件的特性进行了雷诺数修正,并利用发展的性能仿真程序进行计算和对比。结果表明,在高空低马赫数下,雷诺数对大涵道比涡扇发动机性能影响较大,造成发动机的推力减小约1.98%、耗油率增大约3.04%,同时影响发动机的喘振边界及共同工作线,降低其可用稳定裕度。

关 键 词:雷诺数  涡扇发动机  数值仿真  大涵道比  性能

Abstract:For assessing the Reynolds number's effect on a high bypass ratio turbofan,the correction methods such as Wassell were used for the main component characteristics,and cooperated with a new performance program to simulate the effects of Reynolds number on engine's performance. Results show that Reynolds number has grievous effects on the turbofan in high flight and low Mach number region,the thrust  is declined by near 1.98%,the specific fuel consumption is  escalated by near 3.04%,the stall lines and operating lines are affected and the stall margin is  declined as well.
Keywords:Reynolds number  turbofan  simulation  high bypass ratio  performance
