Application Of Naca Aerodynamic Profile With Tubercle Design On Aerogenerators

Abstract

In the aeronautics sector there is one of the most important sections which is the aerodynamic profile with its study and application, which are cross sections that are designed to generate suspension and for the desired fluid to flow over it. For this, I used the NACA4412 profile, modifying its attack profile with the so-called “tubercles”, this in CATIA with simple equations of sines and cosines. And making the design elliptical so that the wind turbine blade can obtain the greatest efficiency, least resistance and great stability when interacting with the fluid. For this, I used the NACA4412 profile, modifying its attack profile with the so-called “tubercles”, this in CATIA with simple equations of sines and cosines. And making the design elliptical so that the wind turbine blade can obtain the greatest efficiency, least resistance and great stability when interacting with the fluid. Once the different designs have been created, the geometry is introduced into FLUENT-ANSYS and the mesh corresponding to the profile is generated and certain working conditions are established, such as speed, degrees and so on. The objective is to be able to determine which of the 4 types of profiles that have been created is the best in terms of efficiency so that a wind turbine can use it. Obtaining a good value in lift coefficient and a very low value in resistance.
