The work presents a fundamental study, which is dedicated to smooth-surface separation phenomena of turbulent flows at subsonic flow speeds, and, as a second point, to corner-flow separation in the junction of the test model geometry and the wind-tunnel-side wall and the arising three-dimensional flow features. Successful RANS model modifications are presented, verified and validated.
