Numerical Simulation of Aerodynamic Performance ofWing with Bionic Non-smooth Surface

According to the resistance reduction characteristic of bionic non-smooth surface, two kinds of bionic models were proposed to modify the NACA 2412 airfoil. Non-smooth rectangular stripes with the same quantity and size were arranged on the upper and lower surface of the wing, respectively.With the software Fluent, the aerodynamic performances of the original wing and two kinds of bionic non-smooth wing under different attack angles were analyzed by Renault average method. The results show that attaching stripe structures to the bottom surface of the wing improves the aerodynamic performance of the wing, while attaching stripe structures to the top surface harms the aerodynamic performance of the wing.
