PhD project:

Title: Numerical analysis of the interaction between a Rotating Detonation Combustor and an axial turbine

A Rotating Detonation Combustor (RDC) generates a complex, unsteady flow pattern that would reach the inlet of the High-Pressure Turbine (HPT) in a gas turbine engine environment. The interaction between this flow and the turbine may have adverse effects on the performances and operability of both the turbine and the combustor. The objectives of this project are to improve the understanding of the aerodynamic interactions between these components, to identify the potential issues generated by the coupling between a RDC and a HPT, and to investigate innovative solutions to solve them. The work will be primarily performed through numerical computations (using AVBP from CERFACS), and it will probably be supported by an experimental campaign at the ENSMA-Pprime laboratories (t.b.a.).

Supervisors: Dr. Said Taileb, Prof. Marc Bellenoue, Prof. Thierry Poinsot

Mentor: Dr. Simone Salvadori.

Planned secondments:

CERFACS Toulouse (6 months, from 11/2021 – 04/2022)
ENSMA-Pprime Poitiers (t.b.a.)

Background:

Gregory Uhl graduated from TU Munich with a B.Sc. degree in mechanical engineering and a M.Sc. degree in aerospace. During his studies, he conducted a variety of numerical analyses and experimental validations in the fields of thermodynamics and fluid mechanics. He joined the Institute of Internal Combustion Engines at TU Munich after his graduation to work on the optimization of a multi-physics combustion model, using machine learning models and genetic algorithms. In October 2021, he joined the INSPIRE-ETN project as a PhD fellow within Safran, ENSMA and CERFACS.
