Keywords: free-stream turbulence, transistion, pressure gradient

Experimental and numerical study of laminar-turbulent transition is performed for a number of flow cases covering a range of flow Reynolds numbers, turbulence intensities and pressure gradient distributions. The flow parameters are typical for turbomachinery applications and the focus is on validation of transition model for transition prediction.
