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 …

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) …

In this thesis a new modeling strategy for simulations of lean hydrogen-air mixtures is
developed and validated. The goal is the development of a new semi-empirical correlation …

In this study flame dynamics in homogeneous hydrogen-carbon monoxide-air (H 2-CO-air)
mixtures are investigated in an explosion channel. The small scale test rig is a 6 m long …

Darrieus–Landau instability is an essential driving mechanism behind flame acceleration,
especially in the absence of turbulence. Effectively quiescent initial conditions are …

System failure in large-scale electrolyzer and fuel cell installations may cause the formation
of explosive H2–air–steam mixtures. Detonation properties (eg, detonation cell size) and …

Previous studies of flame acceleration and deflagration-to-detonation transition (DDT) in a
partially obstructed channel applying a blockage ratio of 60% and a spacing of 300 mm …

Being decarbonated, hydrogen stands as an interesting candidate to reduce greenhouse
gas emissions. However, its storage and transport in big quantities raise safety concerns …

Flame dynamics features such as flame acceleration, run-up distance and deflagration-to-
detonation transition (DDT) were investigated experimentally (in a 30 m long detonation …

This paper describes a high-pulse-energy frequency-doubled ultraviolet dye laser operating
at a repetition rate of 500 Hz. The pump source is a laser-diode side-pumped Q-switched …
