| 摘 要： | 采用格点格式的有限体积法对RAE2822翼型的气动特性进行了粘流数值模拟，流动模型为雷诺平均NS（RANS）方程。在此基础上系统研究了不同网格类型以及不同湍流模型的计算精准度。通过与经典的试验数据进行确认研究，得出了适宜二维跨音速粘性流动计算的网格拓扑分布规律，并总结出了适宜的湍流模型。

| Abstract: | In this paper a node- centered finite volume method is applied to study the accuracy of viscous numerical simulations of the RAE2822. The effects of different grid structures and turbulence models based on the simulations are elaborated systemically. The CFD calculations are validated with the classical wind tunnel test results. The guidelines of grid topology distribution and turbulence models suitable for 2D transonic viscous flow are summarized. |
