摘要
The complex separation flow caused by icing will lead to the deterioration of aerodynamic performance, especially stall behavior. The accurate prediction of aerodynamic performance and the thorough investigation of mechanism under icing condition depend on the precise solution of the separated flow field. With the improvement of computational fluid dynamics methods especially turbulence simulation, the numerical simulation can reflect the physical nature of separated flow as well as provide precise and complete results. In terms of the application of three typical turbulence simulation methods, Reynolds Averaged Navier-Stokes(RANS), Large Eddy Simulation(LES)and RANS/ LES, a comprehensive review of recent research progress in numerical simulation on the prediction of stall behavior and characterization of separated flow are presented. Furthermore, the summary and outlook of the development tendency are also proposed in the aspects of high-fidelity ice shapes, new type turbulence simulation methods, deep analysis of unsteady features and real time coupling analysis of separated flow. © 2023 AAAS Press of Chinese Society of Aeronautics and Astronautics.
