Furthermore, the obtained pressure distribution, velocity contours, and streamlines illustrate how the VGs enhance the aerodynamic performance of the NACA 63-215 airfoil.īaldacchino, D., Ferreira, C., Tavernier, D.D., Timmer, W.A., and Van Bussel, G.J.W., Experimental Parameter Study for Passive Vortex Generators on a 30% Thick Airfoil, Wind Energy, vol. The results showed that the novel configuration improves the maximum lift coefficient of the NACA 63-215 airfoil with a decrease in the drag coefficient at high angles of attack in addition, the lift/drag ratio was also increased. The predicted aerodynamic coefficients agreed well with the experimental results. In the second, a novel configuration was used in which the length and height of the VGs are increased to enhance the aerodynamic performance. In the first, a validation of an experimental study of an airfoil with VGs placed at 10% of the leading edge was carried out. Two different configurations of VGs were studied. The Reynolds averaged Navier-Stokes equations with the shear stress transport k−ω turbulence model were solved in these simulations to investigate the effects of VGs height and length. A numerical investigation was carried out to study the effectiveness of vortex generators (VGs) on the aerodynamic performance of the NACA 63-215 airfoil.
