Plunging Airfoil: Reynolds Number and Angle of Attack Effects

Natural flight has consistently been the wellspring of many creative minds, yet recreating propulsive systems natural flyers is quite hard and challenging. Regarding design, biomimetics offers a wide variety solutions that can be applied at low Reynolds numbers, achieving high performance maneuverability systems. The main goal current work to computationally investigate thrust-power intricacies while operating different reduced frequencies, nondimensional amplitudes, mean angles attack oscillatory motion NACA0012 airfoil. Simulations are performed utilizing RANS (Reynolds Averaged Navier-Stokes) approach for number between 8.5×103 3.4×104, frequencies within 1 5, Strouhal numbers from 0.1 0.4. influence angle-of-attack also studied in range 0? 10?. outcomes show ideal operational conditions diverse results regarding correlations on aerodynamic coefficients efficiency widely explored.
