Premixed Hydrogen-Air Explosion Experiments in a 1-Meter Open-ended Channel with Cylindrical Obstacle under Atmospheric Conditions

This dataset supports the article: “Mechanistic and Statistical Characterisation of DDT in Hydrogen–Air Explosions through Cylindrical Obstacles at Atmospheric Conditions”, Combustion Science and Technology, 2025, DOI: 10.1080/00102202.2025.2569620. It contains:Experimental_Data_Summary: Overview table summarizing all experiments, including DDT outcome and sensor data.Pressure_MassFlow_Combined_Data_CSV: Raw .csv files with explosion pressure data (PS1–PS4) and hydrogen–air mass flow data for each test.Flame_Front_Position_Data_CSV: Flame front position over time extracted from high-speed imaging and postprocessing, organized by Zone 1 and Zone 3. (Currently in progress; available upon request by contacting [e-mail].)Data_Statistics: Summary tables in PDF format showing pressure distributions statistics and DDT frequency across equivalence ratios.Not all experiments include flame imaging. Data files are named according to experiment IDs.If interested in further details or requiring additional clarification, please contact the authors directly at [e-mail].
