Abstract

The experimental investigation of the incompressible flow around a three element airfoil was
carried out to study the effect of angle of attack and Reynolds number. The work started with designing, fabricating and testing the multi-element airfoil in the UPM low speed wind tunnel. The results of the experiment were studied in terms of the coefficient of pressure. The results show delay in flow separation and continuity in pressure distr ibution for studied angles of attack and Reynolds numbers. The performance of multi-element airfoil was compared to a single element airfoil.
