The present paper presents the transfer to the virtual environment and CFD analysis of physical experiments on the explosions of air-hydrogen mixtures carried out on a transparent stand, in the shape of a rectangular spiral. The shape of the stand was designed with the intention of directing the explosion process of the fuel mixture on a rectangular-spiral trajectory, with angles of 90 degrees. The free volume inside the spiral was sectioned by four foiled shutters into four ignition/combustion chambers, the first...

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...
