A modified algebraic model of the laminar-turbulent bypass/natural transition was implemented into the in-house numerical code for the simulation of the compressible turbulent flow using the RANS equation closed by the two-equation k-ω TNT turbulence model. The model was verified by the ERCOFTAC test cases for various boundary-layer flows and applied for the simulaton of the transitional flow in turbine blade cascades.
