Dataset: COMPARATIVE STUDY OF HYDROGEN ADDITION EFFECTS ON FLAME STABILITY AND POLLUTANT EMISSIONS IN JET-A1 AND SAF/JET-A1 LEAN LIFTED SPRAY FLAMES Samarjeet Singh, Fabian P. Hagen, Stefan R. Harth, Dimosthenis Trimis Engler-Bunte-Institute, Division of Combustion Technology, Karlsruhe Institute of Technology, Karlsruhe, 76131, Germany Overview This dataset contains flame imaging, lean blowout (LBO), and pollutant emission data associated with the manuscript published in the Journal of Engineering for Gas Turbines and Power. The dataset supports the experimental investigation of combustion characteristics for Jet-A1, SAF/Jet-A1 blends, and hydrogen (H2) fuel mixtures under varying operating conditions. Experimental Dataset Description Figure 2 Time-averaged inverse Abel-transformed OH* images for pure Jet-A1 and SAF/Jet-A1 fuel blends at two specific thermal power conditions, with air inlet temperatures of 473 K and 673 K. Figure 3 Time-averaged OH* chemiluminescence images, reconstructed using inverse Abel transformation, for varying hydrogen (H2) contents in Jet-A1 and SAF/Jet-A1 fuel blends at an air inlet temperature of 473 K. Figure 4 Time-averaged OH* chemiluminescence images, reconstructed using inverse Abel transformation, for varying hydrogen (H2) contents in Jet-A1 and SAF/Jet-A1 fuel blends at an air inlet temperature of 673 K. Figures 5 and 6 Lift-off height and flame spread measurements derived from the OH* chemiluminescence images presented in Figures 3 and 4. Figure 7 Lean blowout (LBO) limits for varying hydrogen (H2) blending ratios in Jet-A1 and SAF/Jet-A1 combustion operations. Figure 8 Variation of NOx and CO emissions with specific thermal power for Jet-A1 and SAF/Jet-A1 fuel blends. Figure 9 Variation of NOx and CO emissions with hydrogen (H2) addition in Jet-A1 and SAF/Jet-A1 combustion operations.
