Hydrogen is a key pillar in the global Net Zero strategy. Rapid scaling up of hydrogen
production, transport, distribution and utilization is expected. This entails that hydrogen …

Aiming to gain sufficient data to develop methods capable of predicting and evaluating the
danger of potential explosion or even detonation hazards associated with industrial process …

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 …

Numerical simulations were performed to study flame acceleration and deflagration-to-
detonation transition (DDT) in hydrogen-air mixture in a channel with a two-dimensional …

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 …

There have been many studies concerning on the influence of obstacles on gas explosion,
but the understanding of some phenomena is still not clear, such as explosion overpressure …

In order to investigate the flame behavior of syngas/air mixtures after leakage in industrial
scenarios. A series of fence-type obstacles with a blockage ratio of 0.3 were installed in a …

Combustion wave propagation in a channel containing a stoichiometric hydrogen-air
mixture and an array of obstacles was investigated, aiming to explore the effects of …

The influence of heptafluoropropane (CF 3 CHFCF 3) with different barrier arrangements on
the prevention of methane-air explosions in semi-closed pipes is examined in this research …

This study offers a detailed validation of Large Eddy Simulation (LES) for lean H 2/CH 4/Air
deflagrations in an obstructed tube. An exhaustive validation is conducted against detailed …
