Numerical investigation on the combustion characteristics of premixed NH3-air flames using gliding arc plasma

This dataset supports the manuscript entitled “Numerical investigation on the combustion characteristics of premixed NH₃–air flames using gliding arc plasma”. Ammonia (NH₃) is a carbon-free energy carrier with broad application prospects, but incomplete combustion can generate NOₓ and other pollutants. Recent studies have shown that gliding arc plasma can effectively reduce NO emissions.In this study, we propose a numerical model that couples plasma reactions with combustion reactions to analyse the effects of plasma on the combustion characteristics of NH₃–air flames and the mechanisms of NO formation and reduction. The dataset includes:Experimental data:Measured NH₃ conversion rates under plasma conditionsOptical emission spectra at different NH₃ equivalence ratiosNumerical simulation data:Species evolution with ionization timeTemporal evolution of plasma reactionsSensitivity analysis of NO formationReaction pathway analysis of NOThis dataset provides valuable insights into the NH₃ conversion process and NO emission control mechanisms under plasma-assisted combustion.
