The effects of Reynolds number on airplane aerodynamic characteristics

摘要: 采用CARDC自主开发的基于非结构混合网格技术的大规模并行解算器MFlow，对运输类飞机和战斗机气动特性的雷诺数影响规律进行了研究。通过对不同翼型气动特性的雷诺数影响进行数值模拟研究，探讨了雷诺数对运输类飞机和战斗机气动特性影响不同的原因，得到了翼型厚度和弯度是雷诺数影响气动特性的关键参数的结论。

Abstract: The effects of Reynolds number on aerodynamic characteristics of aerotransport and fighter are studied with the unstructured mixed grid flow solver MFlow developed by CARDC. The different aerodynamic behavior between aerotransport and fighter are studied with the numerical simulation of different airfoils.The thickness and camber are found to be the key parameters to the effects of Reynolds number on aerodynamic characteristics.
