ECN9 Topical areas: Based upon feedback collected at ECN8 and in months following, 5 different topical areas for ECN9 have been selected: • Hydrogen injection • Intake-injection Spray G and Spray M • OME and methanol diesel combustion • Ammonia injection and combustion • Battery safety and thermal runaway Previous “gasoline” and “diesel” topics into areas of physical interest have been consolidated and new topics started in hydrogen and battery safety. ECN participants are in the process to select specific injectors and target boundary conditions to feature at ECN9. Please, confirm if new experimental or CFD research using ECN injectors in these areas are expected, and if people are interested in participating in the scientific committees under these topics. In addition to hydrogen, research using renewable/sustainable liquid fuels are expected. Applications within engines at aviation combustion conditions, falling into these topics, are guessed. Looking forward to seeing you at 9 ECN 2023! Please, for info refer to: Alessandro Montanaro – alessandro.montanaro@stems.cnr.it tel. mobile +39 3389558678 tel. office +39 0817177223
