摘要:

结冰触发的复杂分离流动将导致翼型气动性能特别是失速特性全面恶化。结冰状态气动特性的准确预测和流动机理的深入剖析依赖于分离流场结构的精确求解。随着计算流体力学特别是湍流模拟方法的不断完善,数值模拟能够更为清晰和完备地反映非定常分离流场的细节特征及物理本质、提供更加翔实和丰富的气动力数据。从雷诺平均(RANS)、大涡模拟(LES)和RANS/LES这3类典型湍流模拟方法的应用层面出发,综合评述了近年来数值模拟研究在翼型结冰状态失速特性预测与分离特征描述等方面取得的主要进展,并从高精度冰形构造、新型湍流模拟方法、深层次非定常特性、实时耦合分析等方面对现阶段研究发展的相关趋势进行总结和展望。

Abstract:

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.

Key words: iced airfoil, separated flow, Reynolds Averaged Navier-Stokes (RANS), Large Eddy Simulation (LES), RANS/LES
