Simulation of Reynolds Number's Effect on Performance of High Bypass Ratio Turbofan
摘要
Abstract
For assessing the Reynolds number’s effect on a high bypass ratio turbofan,the correc-tion 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.Re-sults 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.关键词
