• The relationship between the flow around an airfoil and the geometrical shape has been important in the previous research. Therefore, very little study is currently available in the published literature on the relationship between the flow around on the airfoil and the geometrical surface pattern, the surface roughness, respectively. In this study, the geometric structure was added to the airfoil by ball-end milling. And then, the influences of surface pattern, flow velocity, and attach angle, on the flow around an airfoil were examined by using the visualization system and the Gottingen-type wind tunnels with six-component balances. From the experimental results, it is shown that the lift force and the drag force decrease when a geometric structure is added to the airfoil.
