Hydrogen is one of the most promising renewable energies that has been observing rapid
development over the past years. Recent accidental explosion incidents and the associated …

The accidental release of hydrogen into enclosures can result in a flammable mixture with
concentration gradients and possible deflagration-to-detonation transition (DDT). This …

Hydrogen energy is expanding world-widely in recent years, while hydrogen safety issues
have drawn considerable attention. It is widely accepted that accidental hydrogen release in …

The risk of hydrogen combustion after the Fukushima nuclear accident has always been a
topic of concern for the nuclear power industry. In the hydrogen risk assessment of …

In this paper, we simulated the change in hydrogen behavior according to a Passive
Autocatalytic Recombiner (PAR) under oxygen depletion conditions and compared the …

Numerical simulations were performed to study the effect of composition gradient and
obstacle arrangement on detonation initiation in fuel-rich hydrogen-air mixtures. A third …

It is necessary to evaluate the released gases distribution (especially hydrogen) to avoid
hydrogen accumulation and maintain containment integrity against the pressure loads due …

Self-sustaining modes of detonations in non-uniform mixtures for hydrogen and oxygen are
numerically studied. Concentration gradients are set vertical to the direction of detonation …

Passive autocatalytic recombiners (PARs), owing to its excellent hydrogen removal
capability and passive characteristic, have been widely utilized to prevent the potential …

An uncertainty analysis based on the Latin Hypercube Sampling (LHS) method and
MELCOR code for hydrogen production during a SA in WWER1000 nuclear reactor is …
