本文对NACA 0015翼型的静、动态失速绕流进行了数值模拟。对于CFD应用来说，这些构型的处理是一项非常具有挑战性的任务。为了得到空间收敛的解，采用了不同的方法来计算静翼型和变桨距振荡翼型的湍流流动：2D RANS、3D RAN和DES方法，并使用越来越精细的网格。本文的主要结论是，在目前的建模能力下，对静态失速的预测还不成熟，更重要的是动态失速的预测还不成熟
This paper presents numerical simulations of the flow around a NACA 0015 airfoil at static and dynamic stall. The treatment of these configurations is a very challenging task for CFD applications. The turbulent flow around the static and in pitch oscillation airfoil is computed using different approaches: 2D RANS, 3D RANS and DES methodologies and with finer and finer meshes in order to try to reach a space converged solution. The main conclusion of the paper is that the prediction of static and all the more dynamic stall is not mature with present modeling capabilities.Copyright © 2004 by ASME
