Numerical simulations were carried partly for the standard computational domain with various outlet boundary conditions by the algebraic transition model of Straka and Příhoda (2014) connected with the EARSM turbulence model of Hellsten (2004) and partly for the computational domain corresponding to the geometrical arrangement in the wind tunnel by the gamma-zeta transition model of Dick et al. (2012) with the SST turbulence model. Numerical results were compared with experimental data. The agreement of numerical results with experimental results is acceptable through a complicated experimental configuration.
