Close knowledge gaps, develop and validate suitable models for phenomena relevant to release and mixing of LH2. Develop empirical and semi-empirical correlations when applicable. The phenomena include, but are not limited to

  • Flashing multiphase, multicomponent release phenomena
  • Mass and heat transfer including phase transition (evaporation, condensation and freezing of contaminants) in pools, plumes, jets and sprays
  • Free cryogenic jet principle structure, morphology and behaviour in realistic conditions including flammable envelope
  • Heat transfer effect on hydrogen concentration in impinging and/or wall attached jets
  • Effect of wind speed and direction on large-scale LH2 releases
  • Release and dispersion in confined and obstructed spaces, including pressure-peaking phenomena
