An experimental investigation on explosion behavior of non-uniform methane/air explosion
in obstructed duct with different blockage ratios is conducted. The methane/air mixture that …

In this study, a three-dimensional, high fidelity LES of a fully premixed, lean hydrogen-air
deflagration, in a confined and obstructed channel is performed. The experimental …

An inhomogeneous hydrogen-air mixture is induced once hydrogen leakage occurs, and an
explosion may be triggered due to an accidental ignition with sufficient strength. The effects …

In this study the hazardous potential of flammable hydrogen‐air mixtures with vertical
concentration gradients is investigated numerically. The computational model is based on …

Numerical simulations were performed to study flame acceleration (FA) and deflagration-to-
detonation transition (DDT) in non-uniform hydrogen-air mixtures in an obstructed channel …

This study explores the complex mechanisms driving flame acceleration (FA) in hydrogen/air
mixtures with transverse stratification, using high-fidelity 3-D Large Eddy Simulations (LES) …

A methodology for the computationally efficient CFD simulation of hydrogen-air explosions
