In a research study focused on advancing clean alternative fuels and high-energy-density power systems, a non-premixed micro swirl combustor designed for hydrogen and air was developed. The experiment compared flame morphologies in confined and free spaces, evaluating the impacts of inlet parameters on combustion characteristics and radiation performance. The study found that by preventing external air ingestion into the combustion chamber, the recirculation zones' area was reduced. The flame exhibited varying characteristics in confined and free spaces, with flame height influenced by air flow rates. The research highlighted the importance of factors like flow velocity and equivalence ratio in determining combustion stability and wall temperature distribution. Notably, the study identified an optimal equivalence ratio of 0.79 for achieving the highest radiation energy and efficiency, showcasing the potential of hydrogen as a zero-carbon fuel. The work emphasized the significance of sustainable energy solutions in combating greenhouse gas emissions and addressing global climate change challenges.
