The first one is the nominal regime with zero incidence angle involved in the ERCOFTAC Database CFD-QNET and the second one with the incidence angle +20o corresponds to an overload operation regime. Advanced mathematical models with two various models of the bypass transition to turbulence were applied for the simulation of different regimes of transonic flows with attached and separated flows. Transition models proposed by Dick et al. (2012) and by Menter et al. (2015) are based on transport equations for the intermittency coefficient. Numerical results were compared with experimental data based on the optical and pressure measurements.
