Abstract

In recent years, in high-altitude long-time navigation, UAVs have attracted much attention due to their advantages of long-range and unmanned working characteristics. The working environment of this kind of UAV is thin, which often leads to this kind of aircraft being in an environment with a low Reynolds number. This article sets the flight speed to 10m/s and the Reynolds number to 6.8e + 5 for comparative analysis of different airfoils at the maximum position. Use ANSYS Fluent fluid simulation to solve and calculate the geometric model and mesh division of airfoils. Simulate and calculate using the K-SST turbulence model and pressure-based solver. By selecting the common two-dimensional models of NACA2312 and NACA2412 to reduce computational complexity, it is possible to quickly simulate airfoils with different curvature positions through both simulations. By comparing and analyzing the lift coefficient, drag coefficient, pressure cloud map, and velocity cloud map of NACA2312 and NACA2412, reference can be provided for the selection of airfoils for low-speed aircraft and aircraft takeoff and landing at low Reynolds numbers.
