Simulation of Compressible Flow Through the Tip-Section Turbine Blade Cascade with the Unsteady Interaction of the Shock Wave with Shear Layers
Straka P., Příhoda J., Bobčík M.
Abstract:
The contribution deals with the numerical simulation of compressible flow through the tip-section turbine blade cascade with the supersonic inlet boundary conditions. The simulation was carried out by the in-house numerical code using the explicit algebraic Reynolds stress model completed by the bypass transition model with the algebraic equation for the intermittency coefficient. The simulation was focused particularly on the shock-wave/boundary layer interaction resulting in combination of the bypass transition and the separation induced transition.
Keywords:
