Objectives: The acoustic response of acoustic damping systems and burners will be studied using an approach that combines experimentation, numerical simulation, and modeling. The objectives are threefold: (a) to examine the impedance of burner models representative of technologies developed by SAFRAN, (b) to develop suitable acoustic attenuation systems, and (c) to test the developed components under laboratory conditions and in conditions representative of real-world scenarios.

Profile: Master in Science (Aerospace Engineering, Mechanical Engineering) with training in fluid mechanics. An interest in acoustics and experimental work is a plus. Skills in data processing and programming languages (Python) are appreciated. Ideally, knowledge of numerical simulations CFD/CAA. Proficiency in written and spoken English. Desired start of the thesis: October/November 2024.

Funding: ANRT CIFRE with the company SAFRAN Aircraft Engines. Position mainly based at IMFT, with occasional immersions at SAFRAN.

Supervision:   IMFT, T. Schuller, L. Selle et T. Poinsot. SAFRAN : G. Fournier, Abel Faure- Beaulieu et Y. Méry
