Abstract
The analysis in aerodynamic performance has been a recurring theme in engineering research. However, the objectives are to determine the optimal angle of attack as well as the coefficient of support of the profile. This fact increase of cargo transported, fuel consumption and others. However, several phenomena occur in the airfoils, among them the Coanda Effect, which basically consists in adhesion of the flow on surface, generating a pressure gradient on the aircraft leading edge, causing one remain flow close to the surface of the wing. Understanding of this phenomenon is very important to determine the angle of attack can be changed to reduce the forces in turbulent regime. This research investigate the NACA 23012 profile of the EMB 110 - Bandeirante aircraft a relevant aircraft to national aviation. The main purpose is verifying the drag and lift coefficients for one range of angles by CFD simulation at JavaFoil and Star CCM+. To this was compared the processing time and the variables calculated by them to a better applicability.
