... of secondary flow phenomena. This article experimentally investigates the secondary flow effects in the 3D-optimized shrouded stator of the TUDa-GLR-OpenStage, representative of a transonic high-pressure compressor front stage, and its susceptibility to typical hub leakage flows. The impact of stator hub...

... layer was slightly smaller than the experimental boundary layer. The uncertainties of the experimental data were calculated using the propagation of uncertainty equation [ 18 ] and Eq. (14) . This formulation has been omitted here for conciseness. Equations (12) – (14) derive the mass-averaged...

... challenges. Numerical analyses of the fan with a uniform flow at the inlet and that exposed to the distorted flow were performed. These required the use of a full-annulus unsteady time-marching computational fluid dynamics (CFD) model, which was validated with experimental data obtained at a test rig...

...Isak Jonsson; Srikanth Deshpande; Valery Chernoray; Oskar Thulin; Jonas Larsson This work presents an experimental and numerical investigation of the laminar-turbulent transition and secondary flow structures in a turbine rear structure (TRS). The study was executed at engine representative...
