Description	A modified algebraic model of bypass transition was implemented into the in-house numerical code for the simulation of 2D compressible turbulent flow using the RANS equations and the k-omega turbulence model. The intemittent character of flow in the transition region is described by the algebraic relation for the intermittency coefficient and by empirical relations for the onset and the length of the transition region. The modified algebraic model considers different intermittency coefficient in the boundary layer and in the outer turbulent stream. The proposed model was verified by means of test cases ERCOFTAC covering boundary-layer flow with various free-stream turbulence and pressure gradient. Further, the model was applied for the simulation of the transitional flow through a turbine blade cascade and around the NACA 0012 aerofoil.
