Abstract

Aerodynamic behavior of an AIRFOIL with circle, right and inverse triangle shaped DAMAGE was numerically investigated. The flow through the DAMAGE was driven by the pressure differential between the upper and lower wing surfaces. For all DAMAGE shapes, the results showed that the flow could be categorized as weak or STRONG JETs. The jet exited the rear of the DAMAGE; its size was determined by the width of the rear part of the hole and was dependent on the shape of the DAMAGE. Generally, when compared with an undamaged model, increasing the angle of attack for a DAMAGEd model resulted in increased loss of lift coefficient, increased drag coefficient and more negative pitching moment coefficient. This effect was more severe for the right triangle case. Furthermore, the numerical results were compared with experimental data to study the effiect of a wall on the flow field.
