Blind-prediction: estimating the consequences of vented hydrogen deflagrations for inhomogeneous mixtures in 20-foot ISO containers
Skjold, Trygve; Hisken, Helene; Bernard, Laurence; Mauri, Lorenzo; Atanga, Gordon; Lakshmipathy, Sunil; Lucas, Melodia; Carcassi, Marco; al., et (Peer reviewed; Journal article, 2019-09)This paper summarises the results from a blind-prediction benchmark study for models used for estimating the consequences of vented hydrogen deflagrations, as well as for users of such models. The work was part of the HySEA ... -
Computational fluid dynamics simulations of hydrogen releases and vented deflagrations in large enclosures
Lucas, Melodia; Hisken, Helene; Skjold, Trygve (Peer reviewed; Journal article, 2020-01)This paper presents model predictions obtained with the CFD tool FLACS for hydrogen releases and vented deflagrations in containers and larger enclosures. The paper consists of two parts. The first part compares experimental ... -
Investigation of instability and turbulence effects on gas explosions: experiments and modelling
Hisken, Helene (Doctoral thesis; Peer reviewed, 2018-03-09)Safe design of industrial facilities requires models that can predict the consequences of accidental gas explosions in complex geometries with sufficient accuracy. Computa- tional fluid dynamics (CFD) models are widely ... -
Simulating vented hydrogen deflagrations: Improved modelling in the CFD tool FLACS-hydrogen
Melodia, Lucas; Atanga, Gordon; Hisken, Helene; Mauri, Lorenzo; Skjold, Trygve (Journal article; Peer reviewed, 2021)This paper describes validation of the computational fluid dynamics tool FLACS-Hydrogen. The validation study focuses on concentration and pressure data from vented deflagration experiments performed in 20-foot shipping ...
