Abstract: The contribution deals with testing of an algebraic bypass-transition model for shear flows characteristic for turbomachinery. The transition model based on the algebraic equation for the intermittency coefficient is added to the averaged Navier-Stokes equations with the SST turbulence model. The transition onset and length are given by empirical relations. The modified model considers different intermittency coefficient in the transitional boundary layer and in the outer turbulent stream. The model was verified by means of test cases ERCOFTAC covering boundary-layer flow with various free-stream turbulence and pressure gradient.
