Measurements of laminar burning speeds in ammonia and hydrogen-air mixtures for gas turbines

Major research in sustainable energy is directed at understanding the combustion phenomena of advanced aerospace fuels and their exhaust emissions. Ammonia as a hydrogen carrier provides promising benefits to mitigate fossil fuel scarcity and greenhouse gas emissions. Here, ammonia and hydrogen mixtures are ignited in a spherical chamber to understand their flame characteristics and laminar burning speeds across a range of equivalence ratios. Identifying key combustion parameters like the laminar burning speed supports the development of advanced, sustainable gas turbine systems for alternative fuels.
