CONSIDERATIONS ON THE INVESTIGATION OF EXPLOSION PROPAGATION IN CONFINED SPACES
Abstract
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 pressure peaks and increased flame acceleration. Comparative analysis with computational fluid dynamics (CFD) simulations confirmed the experimental trends and provided a deeper understanding of the shock wave interactions in confined spaces. These findings contribute to the development of improved predictive models for hydrogen explosion hazards, offering valuable insights for industrial safety applications and risk mitigation strategies in environments where hydrogen is used as an energy source. Future work will focus on refining CFD models to enhance the accuracy of explosion simulations under variable confinement conditions.
