摘要

Numerical investigation on a DLR annular turbine cascade is presented. Four turbulence models are applied to reveal the influence of the turbulence models on the validation results. One algebraic (Boldwin- Lomax) and three two-equation κ-ε turbulence models (standard κ-ε, Low Reynolds Chien and Yang-Shih κ-ε models) are tested. The CFD results are compared with the experimental data at the station of 40% of the mid-span axial chord downstream the mid-span trailing edge. All the turbulence models show good agreement with the experimental results, both on pitch-wise averaged quantities and surface contour distributions.
