Resumen

In this work, the aerodynamic lift coecient and the pressure distribution are obtained for an airfoil in subsonic and incompressible ow. Two dierent methods are pursued: the numerical method, by using the uid dynamics software called ANSYS Fluent, and the experimental method, using an air ow bench. Additionally, the Bernoulli equation is evaluated in a convergent-divergent passage using the same air ow bench. The behavior of ow is also characterized by the Mach number and the Reynolds number. The tested airfoil is a symmetrical one. The lift coecient 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 proles are presented for each angle, and a comparison between results from the dierent 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 ow, and the two slopes for the lift coecient curve display an appropriate behavior. A few recommendations are also mentioned for future studies.
