As is well known, hydrogen exhibits a wide flammability range, low ignition energy, and high diffusivity, which create significant explosion risks in storage and handling facilities. Therefore, the development of effective methods and devices for the detection and control of hydrogen explosions is essential to ensure operational safety. This paper presents the development and experimental validation of an explosion control device intended for hydrogen storage systems. The proposed device is based on an optical ult...

This study investigates the propagation of hydrogen explosions in confined environments, focusing on the influence of geometry on explosion dynamics. Experimental models were developed to analyze the impact of spatial constraints on pressure rise and flame acceleration. Key parameters, including maximum pressure, flame front velocity, and pressure rise rate (dp/dt), were monitored and analyzed. The results highlight that changes in propagation direction significantly influence explosion behavior, leading to higher...
