In this work, the aerodynamic lift coefficient and the pressure distribution are obtained for an airfoil in subsonic and incompressible flow. Two different methods are pursued: the numerical method, by using the fluid dynamics software called ANSYS Fluent, and the experimental method, using an air flow bench. Additionally, the Bernoulli equation is evaluated in a convergent-divergent passage using the same air flow bench. The behavior of flow is also characterized by the Mach number and the Reynolds number. The tested airfoil is a symmetrical one. The lift coefficient plot with respect to the angle of attack is presented for each of the methods, with its corresponding slope. A range of angles between 0° and 10° is considered. The pressure profiles are presented for each angle, and a comparison between results from the different methods is carried out. Only a qualitative comparison is viable. The conclusions summarize the results for each method. The comparison indicates a general agreement in the behavior of air flow, and the two slopes for the lift coefficient curve display an appropriate behavior.
