- Abstract
This paper presents numerical results and experimental data of the airflow inside a low-speed wind tunnel made of wood, with a square test section with length of 0.79 m and side of 0.2 m. The experimental tests were performed in the exit region of the tunnel test section using a Pitot tube and a hot wire anemometer. The numerical predictions were obtained by solving the Reynolds-Averaged Navier-Stokes (RANS) equations using the Shear Stress Transport k-ω turbulence model with the ANSYS-CFX® code. A numerical solution of a fully developed turbulent channel flow is also presented for comparison purposes. The numerical values of axial velocity were compared with the measurements in the exit region of the tunnel. The turbulent kinetic energy was compared with experimental data in the central point of the exit cross-section of the tunnel. The results are in good agreement with the experimental data.
