Annotation	The work deals with numerical simulation of transonic turbulent flow in turbine cascades taking into account transition to turbulence. The Favre-averaged Navier-Stokes equations are closed by the SST eddy-viscosity turbulence model or by explicit algebraic Reynolds stress turbulence model (EARSM) with the gamma-zeta-transition model of Lodefier and Dick (2006). The mathematical model is solved by implicit AUSM-type finite volume method. The implementation of transition model does not require case specific input under the assumption that the whole thickness of boundary layer is contained in same block of multi-block grid, which can easily be fulfilled by in the cases considered. The results are shown for 2D tip profile turbine cascade and 2D and 3D SE1050 turbine cascade.
