27 September 2023

We are pleased to inform you that the 87th edition of the FABIG Newsletter is now available on the FABIG website.

FABIG Members are able to download Issue 087 from the Technical Newsletters section of the website (once logged-in) whilst non-Members of FABIG are able to purchase it.

This issue comprises the following:

  • Editorial
    G. Vannier - The Steel Construction Institute (SCI)
  • Fire protection of lithium-ion batteries in electric vehicles
    W. Mrozik1, P. Christensen1, J. McDonald1, R. Wade2 and D. Wickham2 - 1Newcastle University, 2AkzoNobel
    This paper presents the results of a series of full-scale fire tests investigating the use of an intumescent coating material to prevent or extend the time for the initiation of thermal runaway when an electric vehicle battery casing containing lithium-ion battery (LiB) modules is subjected to an external fire.
  • Minimum ignition energy of hydrogen-air mixtures at ambient and cryogenic temperatures
    D. Cirrone1, D. Makarov2, C. Proust2,3, V. Molkov1 - 1HySAFER Centre, Ulster University, 2Institut National de l’Environnement Industriel et des Risques (INERIS), 3Sorbonne University
    This paper describes a study the aim of which was to develop a model for the calculation of minimum ignition energy that only requires hydrogen-air mixture composition and temperature as inputs. The study investigates the use of laminar flame thickness to estimate the critical flame kernel. The validity of the correlation was assessed against previous experiments for hydrogen concentrations in air in the range 9-75% vol. with initial temperature equal to ambient. The applicability of the model was extended to hydrogen-air mixtures formed by releases from storage and equipment at cryogenic temperature, and the correlation was then validated against experiments carried out for the PRESLHY project on hydrogen-air mixture with temperatures in the range 123-293 K.
  • A CFD analysis of liquefied gas vessel explosions
    F. Ustolin1,2, I.C. Tolias1, S.G. Giannissi2, A.G. Venetsanos2, N. Paltrinieri1,3 - 1Norwegian University of Science and Technology (NTNU), 2National Center for Scientific Research Demokritos, 3Università di Bologna
    This paper presents a study of BLEVEs for liquid hydrogen (LH2) vessels using CFD analysis. The CFD model was validated against CO2 BLEVE experiments, and hydrogen BLEVE scenarios were then simulated based on tests conducted in the 1990s for automotive applications. The parametric CFD analysis considered different filling levels as well as initial pressures and temperatures of the tank content with the aim of assessing the extent to which initial conditions influence the resulting blast wave.
