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。
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 aerody- namic behavior between aerotransport and fighter are studied with the numerical simulation of different air- foils. The thickness and camber are found to be the key parameters to the effects of Reynolds number on aero- dynamic characteristics.
