Abstract

This article aims to validate a model of aircraft wing profiles for the aeroacoustic and aerodynamic study of the NACA 0012 profile, through numerical simulations using the ANSYS Fluent package. The aerodynamic simulation is validated using the URANS method and the turbulent K-omega SST model for pressure, drag, and lift coefficients based on experiments carried out in NASA’s Langley laboratory. After aerodynamic validation, the acoustic simulation is validated using the acoustic theory of Ffowcs Williams and Hawkings, which is included in the software package. The results point to sound pressure values very close to the values of the experiments carried out at the BANC III conference for the trailing edge at angles of attack from 0 to 6° and frequency ranges from 500 Hz to 5000 Hz. The use of the software proved to be accurate for the proposed model. For more than 6°, the drag coefficient values start to distance themselves from the experimental results due to software limitations in calculating the beginning of detachment at the trailing edge.
