Vented hydrogen–air deflagration in a small enclosed volume
TL;DR: In this paper, small-scale vented hydrogen-air explosions were performed in a transparent cubic enclosure with a volume of 3375 cm3, and the flame propagation was followed with a high speed camera and the overpressure inside the enclosure was recorded using high frequency piezoelectric transmitters.
Journal ArticleDOI
Validation and recommendations for FLACS CFD and engineering approaches to model hydrogen vented explosions: Effects of concentration, obstruction vent area and ignition position
Elena Vyazmina,Simon Jallais +1 more
TL;DR: In this paper, the authors proposed a validation of FLACS CFD code and an engineering tool for the modeling of vented explosions by comparison with recent published experimental results, and suggested recommendations and good practices for the applications of both CFD and engineering models.
Journal ArticleDOI
Medium-scale experiments on vented hydrogen deflagration
TL;DR: In this article, a series of medium-scale experiments on vented hydrogen deflagration was carried out at the KIT test side in a chamber of 1.5 × 1.1 × 3.0 m 3 with different vent areas.
Journal ArticleDOI
Properties of large-scale methane/hydrogen jet fires
Etienne Studer,Didier Jamois,Simon Jallais,Guillaume Leroy,Jérôme Hebrard,Vincent Blanchetiere +5 more
TL;DR: In this article, the main characteristics of large-scale jet fires including visible length, radiation fluxes and blowout have been assessed, and the effects of mixing hydrogen with natural gas will modify the consequences of accidents substantially.
