The verification of the aerodynamic design of the propeller of a horizontal axis wind turbine (HAWT) was per-formed by computational fluid dynamics (CFD). The company Waira Energía S.A.C provided the design to the INACOM / Aula PUCP-CIMNE Group for its analysis. This study was performed to determine some rotor aer-odynamic parameters in quantitative form, such as axial thrust force, torque and power coefficient, and thus compare them with the design parameters. In addition, the study allowed to obtain other aerodynamic param-eters important for a qualitative analysis, such as the external flow pattern, the field of pressures and the field of velocities. All the analysis was performed for different values of the angular velocity of the rotor, in a range between 300 r.p.m. And 500 r.p.m., and wind velocity, in a range between 10 m/s to 15 m/s. Analyzes were carried out in the ANSYS CFXTM software environment. On the other hand, in an additional way, an analytical method based on the combined Momentum and Blade Element Theory (BEM), which incorporates forces and moments per unit length. The coefficients of lift (Cl) and drag (Cd) required in the BEM method were obtained using the free software Qblade. The analytical calculations were made in order to compare them with the results obtained through the numerical simulation and thus verify the computational model. Finally, a prototype of the wind turbine was constructed, in which some parameters were measured to be compared with the ob-tained results. The experimental tests obtained for nominal conditions are in correspondence with the obtained by numerical simulation and the analytical method.
