| 摘 要： | Aerodynamic noise of High-Lift Devices(HLDs) is one of the main sources of airframe noise, and has immediate impacts on the airworthiness certification, environmental protection and security of commercial aircraft. In this study, a novel hybrid method is proposed for the aerodynamic noise prediction of HLD. A negative Spalart-Allmaras(S-A) turbulence model based Improved Delayed Detached Eddy Simulation(IDDES) method coupling with AFT-2017b transition model is developed, in order to elaborately ...
