| Abstract | Hydrogen is carbon-free, so does not produce CO2 emissions when burned. This means hydrogen has the potential to be used for long-term renewable energy storage, or for transportation where energy-density demands cannot be met by battery technology. Burning hydrogen lean (with an excess of oxidiser) can improve efficiency and reduce NOx emissions, but introduces flame instabilities because of the thermodiffusive properties of such a small molecule. These thermodiffusive instabilities are exaggerated by turbulence-flame interactions, which results in significant uncertainty in turbulent flame speed, structure and stabilisation. The proposed simulations will provide a lab-scale numerical twin to experimental turbulent lean premixed hydrogen flames that will be conducted in parallel. The joint experimental-numerical approach will enhance understanding of the fundamental flame physics of hydrogen, and enable development of engineering flame modelling approaches specifically for hydrogen, which can be used to design novel hydrogen combustors with high efficiency and low emissions | |
