摘要

Compared with smooth airfoil, the aerodynamic characteristics of wavy airfoil exhibit some unique features. In order to further explore the aerodynamic characteristics of the wavy configuration, based on the previous wind tunnel tests, a group of wavy airfoils with different geometric shape modified from NACA0030 were designed and then unsteady numerical simulations were carried out in details to investigate the effect of waviness on the vortical structure in the flow field and overall aerodynamic characteristics in low Reynolds number (Re=12×104) region. Final results show that, compared to the smooth airfoil, the separation flow for the wavy airfoil is more obvious, and the lift and its slope decrease significantly, but the stalling is delayed. The smoother the wavy surface is, the closer the aerodynamic characteristics are to the smooth airfoil. Although the pressure drag of the wavy wing is greater than that of the smooth airfoil, the recirculation generated in the corrugation can reduce the viscous drag.
