Abstract

[fr] Structured meshes have been the preferred approach in turbomachinery computations by Safran Aero Booster and other industries for many years, leading to well-established methodologies that give high confidence in results. However, setting up a structured mesh requires many efforts; advanced geometries like under-stator labyrinths, fillets, cooling holes and other technological effects are often neglected or simplified.
Unstructured meshes can be used to model these complex geometries and avoid geometrical approximations.
This work aims to perform turbomachinery multi-row computations applied to a low-pressure compressor, including technological effects, with unstructured meshes. Results from unstructured computations are compared with those from equivalent structured ones.
The purpose is to verify the ability to run such unstructured computations within the company, but also to verify the behaviour of mixing planes with unstructured meshes, to determine if unstructured meshes can be used to get a better understanding of the flow's physics, or if on the contrary, they raise additional questions, while considering their additional cost compared to structured meshes.
