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...

The study of hydrogen explosions in interconnected spaces is essential for safety in industrial and laboratory settings. Due to its highly flammable nature, understanding hydrogen explosion dynamics is essential for risk mitigation. This paper presents an experimental and computational analysis of a hydrogen explosion in a setup with four interconnected chambers. The experimental stand had transparent walls for direct observation. Ignition was initiated to analyze flame propagation, acceleration, and pressure vari...
