    AnnotationNumerical simulations of transonic flows through various turbine cascades in a confined channel which approximates boundaries of real wind tunnel are presented. The boundaries of the wind tunnel are impermeable or there can be permeable tailboards to diminish shock wave reflections. The mathematical model is based on the Favre-averaged Navier-Stokes equations closed by a turbulence model and a transition model. The model is solved by an implicit finite volume method with multi-block grids. Several types of blade cascades with subsonic or supersonic inlet are presented. The results are compared with optical measurements and simulations of periodic cascades. The validity of experimental reference flow parameters in relation to computed flow patterns is discussed.
