Numerical simulation and validation of the aeroacoustic flow field resulting from gust-airfoil interaction

Abstract

This work consists of validation of VAT (Virtual Aeroacoustic Tunnel) for a single airfoil vortical gust reponse. The software used to acquire the simulations results is the Virtual Aeroacoustic Tunnel (VAT), an inhouse code developed by the Computational Aeroacoustics Laboratory of University of Brasília, which obtains the aeroacoustics field by the solutions of Navier-Stokes, Euler or Linearized-Euler equations in its compressible formulation through volume elements discretization. The work is part of the Silent Aircraft project sponsored by Embraer - Brazilian Aeronautics Enterprise and associated with University of Brasília among others.
