We report here the results of a study on measurements and prediction of laminar-turbulent
transition at high free-stream turbulence in boundary layers of the airfoil-like geometries with presence
of the external pressure gradient changeover. The experiments are performed for a number of flow
cases with different flow Reynolds number, turbulence intensity and pressure gradient distributions.
The results were then compared to numerical calculations for same geometries and flow conditions.
The experiments and computations are performed for the flow parameters which are typical for
turbomachinery applications and the major idea of the current study is the validation of the turbulence
model which can be used for such engineering applications.
