H2POWRD Research Highlight: Research on RDC Exhaust Mixing at IWDP 2026

Following our overview of the H2POWRD team's participation at the 14th International Workshop on Detonation for Propulsion (IWDP 2026), we are pleased to highlight another research contribution from the H2POWRD Marie Skłodowska-Curie Actions Doctoral Network.

Doctoral Candidate Eiki Mori (Safran) presented his latest research at IWDP 2026 in Tokyo, Japan.

His research investigates the physics of mixing RDC exhaust gas with cold gas in the ejector, enabling the integration of a subsonic turbine with the RDC by damping pressure and temperature perturbations while cooling the exhaust. Designing the transition duct and optimizing its geometry are key to preserving pressure gain while damping and stabilizing the flow from the RDC exhaust.

The accompanying figure shows a LES result of the temperature field in the ejector and transition duct, providing insight into the complex flow and mixing processes within the system.

This research was carried out within the H2POWRD Marie Skłodowska-Curie Actions Doctoral Network (Project No. 101169009), which brings together leading academic and industrial partners to advance research and training in hydrogen-based propulsion systems.

We congratulate Eiki Mori👏on presenting his work at IWDP 2026 and representing the H2POWRD consortium.
