Effect of Mechanical Ventilation on Accidental Hydrogen Releases—Large-Scale Experiments
Lach, Agnieszka; Gaathaug, Andre Vagner (Peer reviewed; Journal article, 2021)This paper presents a series of experiments on the effectiveness of existing mechanical ventilation systems during accidental hydrogen releases in confined spaces, such as underground garages. The purpose was to find the ... -
Laminar burning velocity of the dimethyl carbonate–air mixture formed by the Li-ion electrolyte solvent
Henriksen, Mathias; Vågsæther, Knut; Gaathaug, Andre Vagner; Lundberg, Joachim; Forseth, Sissel; Bjerketvedt, Dag (Peer reviewed; Journal article, 2020)If a Li-ion cell fails and the electrolyte leaks out into air, a flammable premixed gas cloud can be formed. The electrolyte combustion energy is 65–70% of the total energy content of the cell. The main objective of this ... -
Modeling and simulation of hydrogen flow in a maritime fuel cell system
Valand, Stian (Master thesis, 2022)The climate change challenge is one of today's greatest challenges, and the need to reduce emissions is more significant than ever. Hydrogen can be a potential zero-carbon fuel, and together with a maritime fuel cell system, ... -
