Hydrogen, known for its high flammability and potential explosive characteristics, presents significant challenges in safety engineering, particularly in enclosed spaces where explosions can lead to catastrophic consequences. This paper presents the results of physical experiments conducted to investigate the linear propagation of hydrogen explosions within confined environments. The experiments were designed to simulate real-world scenarios and assess the factors influencing the extent and characteristics of explosion propagation. Various parameters including initial pressure, hydrogen concentration, confinement geometry, and ignition source location were systematically varied to analyze their effects on explosion dynamics. The experimental setup involved controlled release of hydrogen into enclosed spaces followed by ignition under controlled conditions, utilizing a series of friable obstacles. High-speed imaging with use of Schlieren techniques, pressure measurements, and post-explosion analysis techniques were employed to characterize the explosion phenomena. The findings provide valuable insights into the mechanisms governing hydrogen explosion propagation in confined spaces and offer implications for enhancing safety measures and designing mitigation strategies in hydrogen-related applications. This research contributes to the advancement of knowledge in the field of explosion dynamics and provides a basis for further studies aimed at improving safety standards in hydrogen storage, transportation, and utilization systems.
