Annotation	The work deals with numerical solution of two-dimensional compressible turbulent flow in turbine cascades. Two different geometries are considered. Simulations include subsonic as well as transonic regimes. The turbulence is modelled using algebraic, one-equation, two-equation models and the explicit algebraic Reynolds stress model. The dicretization uses the Roe and AUSM finite volume schemes with higher order upwind interpolation for convective terms. The finite volume grids consist of quadrilateral finite volumes. Numerical results are compared with experimental results in terms of flow-field pattern (shock waves), pressure distribution along the blade surface and of the energy loss coefficient. Whereas the former two parameters are predicted well, the loss coefficient presents a parameter difficult to predict.
