Dynamics and combustion instabilities of Hydrogen/Air flames MEGEP (Mécanique, Energétique, Génie civil & Procédés) https://youtube.com/live/vtZZ7qpEpDI?feature=share Combustion instabilities are encountered in many practical burners, where they can damage systems and compromise operational safety. Understanding and controlling instabilities in hydrogen-air flames is therefore essential to support the transition of the energy sector toward zero-carbon fuels. The objective […]
