Measurements and Prediction of Laminar-Turbulent Transition at High Free-Stream Turbulence and Pressure Gradients
Paper i proceeding, 2012

This paper is focused on measurements and prediction of laminar-turbulent transition at high free-stream turbulence in boundary layers of airfoil geometries with external pressure gradient changeover. Experimental and numerical study is performed for a number of flow cases covering a range of flow Reynolds numbers, turbulence intensities and pressure gradient distributions. The flow parameters in experiments and computations are typical for turbomachinery applications and main motivation of current study is validation of transition models which can be used for transition prediction in such engineering applications. In current work the experimental data are used to validate a transition model by Langtry and Menter which showed good agreement with experiments for all test cases.
