Résumé
[en] This master thesis describes the assessment of secondary flows model for a viscous throughflow solver in the scope of two test cases. They are the classic axial compressor stage CME2 and a multi-stage axial low-pressure compressor with highly loaded blades developed by Safran Aero Boosters.
The review of the literature for secondary flow models has shown that geometrical and flow parameters are of great importance in the formulation of these correlations.
By the comparison with three-dimensional RANS simulations, the assessment of the reliability of different types of correlations for design and off-design conditions, various boundary layer thicknesses and blade geometries has shown that the distributions for the total pressure loss coefficient and deviation angle from Roberts are providing the most promising results.
However, the implementation of Roberts’ correlations in theirs current forms in the throughflow model has not shown a substantial improvement in terms of the prediction of performance maps for the two test cases.
Even tough secondary flows physics are still hardly predictable, such models can be completed by additional terms and coefficients for improving preliminary design applications. Some suggestions are discussed at the end of this thesis.
