运输机机翼、机身和翼身组合体气动特性雷诺数效应的数值模拟研究

Investigation of Reynolds number effects on transport aircraft's wing,fuselage and wing-body by numerical simulation

摘要: 通过CFD方法对运输机单独机身、翼身组合体及不同厚度和弯度的翼型进行了数值模拟研究,分析了雷诺数对机身和翼身组合体气动特性的影响规律,通过雷诺数对有弯度的翼型及旋成体气动特性影响的研究,初步解释了雷诺数对机身和机翼影响差别的原因。

Abstract: This paper focuses on Reynolds number effects for aerodynamics characteristic of fuselage and wing-body,by investigating flow field of fuselage,wing-body and airfoil with different thicknesses and cambers using CFD.The difference of Reynold number effects for fuselage and wing is explained preliminarily.
