The ambitions for tackling global warming initiated by COP27/28 have accelerated the quest for decarbonised energy generation processes and the use of zero-carbon fuels will play an increasingly important role in the future, especially for the UK to meet government net-zero targets. Ammonia, as a carrier of hydrogen, is widely considered a future zero-carbon energy vector. The reactivity of NH3 is often improved through the catalytic production of H2 via partial thermal decomposition from solar heat to form an NH3/H2/N2 mixture, herein denoted D-NH3. However, D-NH3 combustion can lead to a high emission of NOx including the production of N2O – a gas with a greenhouse potential 300 times greater than CO2. Thus, a thorough understanding and improved computational modelling of the premixed combustion of D-NH3 are needed so that the potential of NH3 as an alternative fuel for gas turbines and marine engines can be realised.
This project will utilise advancements in high-performance computing to analyse turbulent premixed combustion of D-NH3 using Direct Numerical Simulations (DNS, where all the length- and timescales of turbulence are resolved without any physical approximations). The resulting data will be utilised to assess the validity and performances of existing modelling techniques for NH3/H2/air combustion in the context of Reynolds Averaged Navier-Stokes (RANS) and Large Eddy Simulations (LES) and new models will be proposed based on physical principles, and machine learning techniques trained based on DNS data.
Siemens Software Ltd. and Renuda will provide in-kind support to this work. Their representatives will form an Impact Advisory Panel (IAP) and support the project by providing an industrial perspective.
