ECM23 workshop # 1: Recent advances in flame acceleration, detonation onset and detonation propagation
The Detonation Team from l'Institut PPrime is organizing one of the four thematic ECM23 workshops scheduled to take place on Tuesday April 25th 2023, one day before the 11th European Combustion Meeting to be held in Rouen, FRA from the 26-28 April 2023
The main objectives of the proposed workshop are to bring leading French and European scientists together to discuss:
- Recent progress and outstanding challenges in flame acceleration, detonation onset and detonation propagation (i.e., experimental, numerical and theoretical)
- Identify/align needs between experimental and numerical research
- Foster collaboration
We are planning for a full-day (9h-17h30) of enriching presentations divided in 4 sessions. Two morning sessions: (1) Three talks from 9h to 10h30 followed by a 30 minute break (10h30-11h); (2) Three talks from 11h to 12h30 followed by a lunch break. The afternoon program will mirror the morning sessions: (3) Three talks from 14h-15h30 followed by a 30 minute break (15h30-16h); (4) Three talks from 16h-17h30 followed
A total of 12 invited talks of 30 minutes each (20-min presentation + 10-min questions/discussion), 2 coffee breaks (30 min each), a 1h30 min lunch and farewell drinks. The generous time allocated for discussion is so that meaningful, extended exchanges can take place among the attendees.

About the organizers
They are members of the Detonation team in the Fluides, Thermique et Combustion Department at l’Institut Pprime (CNRS, UPR 3346, Poitiers, FRA). They work on fundamental and applied research including high-pressure combustion, ideal/non-ideal detonation structure and propagation dynamics, shock-/thermal-ignition, flame acceleration and transition to detonation (DDT), chemical kinetics, detonative propulsion and hydrogen safety. The team’s research activities are primarily fundamental, both experimental and theoretical, with an increasingly strong numerical component based on state-of-the-art in-house and open source tools for simulation of high speed reactive flows. Our team is well-positioned as a reference for advanced applied studies on hydrogen safety, and demonstrated the feasibility of oblique (1989), pulsed (1995) or rotating (since 2000) detonation engines in collaboration with the French aerospace industry (MBDA, ONERA, CNES).
