Comparison of Transonic Flows Through Two Tip-Section Turbine Blade Cascades with Different Flat Profiles
Musil, Josef ; Příhoda, Jaromír ; Fürst, J. ; Luxa, Martin ; Šimurda, David
The contribution deals with numerical simulations of 2D compressible flow through two variants of the tip-section turbine blade cascade with a flat profile for the subsonic inlet. Simulations were realised by means of the OpenFOAM code using the γ-Reθ bypass transition model completed by the two-equation SST turbulence model. Predictions were focused particularly on the impact of the shock-wave/boundary-layer interaction on the flow structure in the inter-blade channel. Beside the effect of the inlet angle on the flow around the leading edge was studied. Numerical results were compared with optical and pressure experimental data.
Simulation of Supersonic Flow Through the Tip-Section Turbine Blade Cascade with a Flat Profile
Musil, Josef ; Příhoda, Jaromír ; Fürst, J.
The contribution presents results of the numerical simulation of 2D compressible flow through the tip-section turbine blade cascade with a flat profile and the supersonic inlet. The simulation was carried out by the OpenFOAM code using the Favre-averaged NavierStokes equations completed by the two-equation SST turbulence model and the γ-Reθ bypass transition model. Predictions carried out for nominal conditions were focused particularly on the relation between the inlet flow angle and the inlet Mach number. Further, the effect of the shock-wave/boundary layer interaction on the skin friction coefficient was investigated. Numerical results were compared with experimental data.
