Master thesis and internship[BR]- Master's thesis : Aerodynamic study of a stator blade with a wavy leading edge[BR]- Internship

Abstract

This thesis, conducted at Safran Aero Boosters (SAB), investigates the potential benefits of using wavy blades inspired by humpback whale flipper tubercles to enhance robustness against high incidence effects in low-pressure compressors. A Python script was developed to design these complex geometries, validated on both cascade and industrial blades. The study compared a wavy blade with a reference blade using the k-epsilon model and k-omega Wilcox turbulence models, highlighting the wavy blade's superior performance. A parametric study was led, pointing out interesting tredns. Despite promising results in specific zones, the application of wavy patterns in an industrial context did not meet the overall performance requirements, raising questions about their effectiveness in turbomachinery.
