“…The size of the computational domain was chosen in such a way so that the blockage effect is negligible. Due to the time demanding computations for the inlet flow velocity 14m/s used in the wind tunnel experiments (Hračov and Macháček, 2020), the velocity of the inlet flow was chosen to be 2.8 m/s (corresponding to the Reynold's number Re = 2.7e4) for the most of performed simulations. Periodic boundary conditions were imposed on side and lower-upper surfaces (cf.…”

“…The flow around U-profiles with the constant side ratio 2 differing in the inner depth of their vertical sides and the effect of the porosity or their flanges at different attack angles were studied in the wind tunnel by Hračov and Macháček (2020). Ledvinková et al (2021) and Ledvinková et al (2022) with the aim to compare simulated results with the experimental ones performed the 2D URANS simulations with the same geometry and conditions.…”

Our contribution is focused on the comparison of the experimental investigations and of the numerical 3D LES simulations of the airflow around sharply edged rectangle with side ratio 2:1. The rectangle object was exposed to the airflow having a given velocity at different angles of the wind attack in the wind tunnel with the aim to obtain the curves of the aerodynamic coefficients and Strouhal number depending on the impact angle. The comparative numerical 3D simulations of the wind tunnel testing were performed using COMSOL Multiphysics and OpenFoam both incorporating the Large Eddy Simulation (LES) method.
