Abstract [en]

Computations of the Turbine-99 benchmark have been performed for two dimensional steady inlet boundary conditions. Three different turbulence models were used: zero equation model, k-ε and shear stress model (SST). The results from the engineering quantities indicate small differences on the mean pressure recovery and the loss factor, while larger differences appear for the wall pressure recovery.
