基于CFD的涡扇发动机推阻分解方法及应用
Thrust-drag bookkeeping method of turbo-fan engine and its application
摘要
Abstract
This paper focuses on the thrust and drag determination of the powered-on nacelle of civil airplanes.The thrust-drag bookkeeping method based on computational fluid dynamics is used to compute the thrust and drag.First,the control volume analysis of a powered-on nacelle is applied to study the computation methods for each force component.Then three test cases are numerically investigated to demonstrate the thrust-drag bookkeeping process and accuracy.The NACA 1-85-75 inlet test case shows that the present method has reasonable accuracy on the inlet spillage drag.The computation results agree well with the experimental data.The DSFR nozzle from the propulsion aerodynamics workshop 2 is used to test the prediction precision on nozzle performance.The results show that the present computation method is well validated.The deviation between the computation result and experimental data is 0.003 to 0.004.The NAL-AERO-02-01 TPS nacelle case is adopted to demonstrate the process of the thrust-drag bookkeeping process.With the bookkeeping method, the nacelle drag variation with Mach number is revealed and associated with the flow phenomena on the nacelle.关键词
