H2POWRD Research Presented at the Journées Écoulements & Fluides à Saclay (JEFS)

Last month, H2POWRD doctoral researcher Mathieu Constant represented ONERA – The French Aerospace Lab and the H2POWRD Marie Skłodowska-Curie Actions Doctoral Network at the Journées Écoulements & Fluides à Saclay (JEFS), organised by Université Paris-Saclay.

During the event, he presented numerical results of the Large-Eddy Simulation (LES) of a Hydrogen/Air Rotating Detonation Combustor (RDC) equipped with a Pintle Injector. The presentation provided an opportunity to introduce the subject of detonative propulsion and to discuss turbulence modelling in relation to the transient injection process occurring in an RDC.

LES is a Computational Fluid Dynamics (CFD) approach that aims to resolve the largest turbulent scales (vortices that in practice are larger than the mesh cell size) of the flow. LES coupled with cost-efficient injector optimisation procedures, LES enables significant improvements in the understanding and design of rotating detonation combustors.

This research has been conducted under the supervision of Dr. Thomas Gaillard, Dr. Dmitry Davidenko, and Prof. Marc Bellenoue. Special thanks are extended to Amaury Anquetil and Prof. Dr. Myles Bohon from Technische Universität Berlin for their support and collaboration.

This project has received funding from the European Union's Marie Skłodowska-Curie Actions Doctoral Network programme under H2POWRD (101169009) Project.
