Abstract
In this research, an experimental comparison was presented to study the effect of air channels on the aerodynamic properties of the asymmetric NACA2412 airfoil, before and after the adenium air channels, the airfoil data was imported and designed by AutoCAD with the work of two models, the first regular and the other a model containing air channels along the airfoil, the design models were then sent in the form of STL files to the printing press to be printed, and to conduct the tests were Use a low-velocity educational wind tunnel. The experimental tests were conducted at three velocities (3.8, 5.1, 6.1) m/s. The lift and drag coefficients were calculated at several different angles of attack under the same conditions and the results were compared to show the effect of channeled on airfoil performance. The results showed that the lift and drag coefficients increase with increasing angle of inclination of the airfoil, and this study also found that channeled leads to a deterioration in aerodynamic performance, especially a decrease in lift and increased drag and thus a decrease in the dynamic efficiency of the channeled airfoil.
