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.<\/jats:p>","DOI":"10.5593\/sgem2024\/1.1\/s06.79","type":"proceedings-article","created":{"date-parts":[[2024,12,4]],"date-time":"2024-12-04T12:26:12Z","timestamp":1733315172000},"page":"633-642","source":"Crossref","is-referenced-by-count":2,"title":["PHYSICAL EXPERIMENTS REGARDING THE LINEAR PROPAGATION OF HYDROGEN EXPLOSIONS IN ENCLOSED SPACES"],"prefix":"10.5593","volume":"24","author":[{"given":"Gheorghe Daniel","family":"Florea","sequence":"first","affiliation":[{"name":"National Institute for Research and Development in Mine Safety and Protection to Explosion, INSEMEX Petrosani","place":["Romania"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolae Ioan","family":"Vlasin","sequence":"additional","affiliation":[{"name":"National Institute for Research and Development in Mine Safety and Protection to Explosion, INSEMEX Petrosani","place":["Romania"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian Bogdan","family":"Simon-Marinica","sequence":"additional","affiliation":[{"name":"National Institute for Research and Development in Mine Safety and Protection to Explosion, INSEMEX Petrosani","place":["Romania"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristian Raul","family":"Cioara","sequence":"additional","affiliation":[{"name":"National Institute for Research and Development in Mine Safety and Protection to Explosion, INSEMEX Petrosani","place":["Romania"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurentiu","family":"Munteanu","sequence":"additional","affiliation":[{"name":"National Institute for Research and Development in Mine Safety and Protection to Explosion, INSEMEX Petrosani","place":["Romania"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3602","reference":[{"key":"ref=1","unstructured":"[1] Calamar A.N., Gaman G.A., Kovacs M., Pupazan D., Lorand T.
