Influence of In-Duct Blockage Ratio on Hydrogen–Air Explosion Behaviour Inside a Vented Duct and in the External Space
Vented hydrogen explosions in ducts can transfer flame and pressure loads to external spaces, yet how internal obstructions regulate this external hazard remains insufficiently understood. Here, a three-dimensional FLACS model was used to examine hydrogen–air explosions with in-duct blockage ratios of 0–66.8%. Results...
