This paper presents the verification of the boundary layer modeling approach, which relies
on a γ-Reθt model proposed by Menter et al.(2006,“A Correlation-Based Transition Model
using Local Variables—Part I: Model Formation,” J. Turbomach., 128 (3), pp. 413–422). This
model was extended by laminar-turbulent transition correlations proposed by Piotrowski et
al.(2008,“Transition Prediction on Turbine Blade Profile with Intermittency Transport
Equation,” Proceedings of the ASME Turbo Expo, Paper No. GT2008-50796) as well as …

The paper presents the verification of boundary layer modeling approach, which relies on a
γ-Reθt model proposed by Menter et al.[1]. This model was extended by laminar-turbulent
transition correlations proposed by Piotrowski et al.[2] as well as Stripf et al.[3] correlations,
which take into account the effects of surface roughness. To blend between the laminar and
fully turbulent boundary layer over rough wall the modified intermittency equation is used. To
verify the model a flat plate with zero and non-zero pressure gradients test cases as well as …
