Hydrogen safety

HyFOAM has been developed within the frame of open-source computational fluid dynamics (CFD) code OpenFOAM® for hydrogen safety including:

  • A high fidelity LES approach with high order weighted essentially non-oscillatory scheme to study the underlying physics of spontaneous ignition in pressurized hydrogen releases [1].
  • Modelling approach for hydrogen explosions [2].
  • Flame-wall interaction [3].
  • Hydrogen jet fires [4].
  • Flame acceleration (FA) and DDT [5], incorporating the effects of concentration gradients in hydrogen/air mixtures [6].
  • Vented hydrogen explosions [8,9]
  • Near-field dynamics of pressurised cryogenic hydrogen [11].
  • Ignited release of cryogenic hydrogen [12].
  • Atmospheric dispersion from large scale spill of cryogenic liquid hydrogen [13].
