Sinusoidal leading-edge wings have shown a high performance after the stall region. In this study, role of smart flaps in aerodynamics smooth and sinusoidal at low Reynolds numbers 29,000, 40,000 58,000 is investigated. Four with NACA 63 4 -021 profile are firstly designed then manufactured by 3 D printer. Beam bending equation used to determine flap chord deflection. Next, wind tunnel tests carried out measure lift drag forces proposed for wide range angles attack, from zero 36 degrees....
In this study, viscous, turbulent, and steady flow around an airfoil near the water surface has been simulated through a numerical method. simulation, Navier-Stokes equations have solved using finite volume method with discretized second-order accuracy PIMPLE algorithm. The Volume of Fraction (VOF) employed to predict free flow. A part simulation results validated experimental data. Besides considering style separation in angles numerous attacks static stall water. For purpose, processed...
Purpose Ground effect is one of the important factors in enhancement wing aerodynamic performance. This study aims to investigate forces and performance a flapping with bending deflection angel under ground effect. Design/methodology/approach In this study, mechanism were designed manufactured based on seagull flight then assembled. It worth noting that capable upstroke as big birds. Finally, model was examined at angles 0° 107° different distances from surface, frequencies velocities...
The aerodynamic performance of fabricated eagle wing with the corrugated trailing edge was investigated experimentally and numerically in this study. In respect, wings were designed by imitating bionic using a 3D printer. Tests on performed wind tunnel for different bending deflection angles, flapping frequencies, angles attack, forward flight velocities. As key parameters, lift thrust forces, lift-to-drag input power compared between simplified wing. results revealed that led force to be...
