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...

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...
