A three-dimensional turbulent flow of a viscous compressible gas through a high-loaded transonic turbine cascade is considered, taking into account the laminar-turbulent transition. Mathematical simulation of the flow is performed using the Reynolds-averaged Navier-Stokes equations and the two-equation k-ω SST turbulence model. Transition modeling is based on the algebraic PTM model. The effect of turbulent flow parameters on the laminarturbulent transition and the kinetic energy losses of the modeling turbine cascade of the TFAST project is investigated.
