The use of ammonia and hydrogen as fuels to decarbonise the heavy transport industry has attracted worldwide attention. In this work, a swirl-enhanced combustion test rig been built investigate emission characteristics non-premixed ammonia/hydrogen flames. blowoff limits were first examined ensure that range stable flames could be achieved. Emissions containing nitric oxide (NO), nitrous (NO2), slip (NH3) unburnt (H2) then measured with variety global equivalence ratios, blending inlet gas...

All diesel-only trains in the UK will be phased out by 2040. Hydrogen and ammonia emerge as alternative zero-carbon fuel for greener railway. Solid Oxide Fuel Cells (SOFCs) provide an prime mover option, which efficiently convert fuels into electricity without emitting nitrogen oxides (NOx), unlike traditional engines. Superior to Proton Exchange Membrane (PEMFCs) efficiency, SOFCs fulfil MW-scale power needs can use directly. This study investigates innovative strategies integrating hybrid...

The extraction of cellular structure feature on the spherical premixed flame surface faces accuracy challenges. Schlieren technique was employed to obtain hydrogen-air flames images in a constant volume vessel at room temperature and atmospheric pressure under an equivalent ratio 0.8 this work. A bio-inspired Cellpose 2.0, driven by deep learning, is innovatively introduced train cell segmentation model combustion field. After labeling training cells different shapes sizes, efficient...

All diesel-only trains in the UK will be removed from services by 2040. High volumetric density, rapid refuelling ability, and sophisticated experience infrastructure logistics make ammonia a perfect hydrogen carrying fuel for rail freight, which urgently requires an economically viable solution. This study conducted novel techno-economic of ammonia-fuelled cell powertrains to compared with current diesel engine-based system emerging direct hydrogen-fuelled system. The results demonstrate...
