The Analysis of Airfoils Based on CFD Simulation

The paper introduces structured grid division, use CFD numerical simulation and FLUNET software to conduct the simulation calculation for flow field of subsonic wing sections, which study the lift-drag characteristics of it. To better illustrate the problem, we use the NACA0003 wings and hex wing sections. This paper calculate lift-drag characteristics of each wing section that in 0.3Ma and 0.5Ma, 0 to 12 attack angles, then compare the lift-drag characteristics in different conditions and analyze from the perspective of flow field.
