PRESLHY WP 4.4. (Ignition above the Pool) Experiment: 20200427_134405; Material of the ground: Concrete07; High of the ignition point: 08cm; Camera: CANON II

To identify and understand the ignition risks associated with situations unique to liquid hydrogen releases, where factors of cryogenic temperatures are significant. Ares of particular interest are: ignition potential at reduced temperature in the vapour phase; electrostatic charging in liquefied/multiphase mixtures; and energetic multiphase mixtures of hydrogen and oxygen.
The key objective is to understand the impact of these particular circumstances on the likelihood of ignition, and to confirm the prioritisation of phenomena for further study within the project.
Phenomena: Ignition above the pool under variable conditions (material of the ground, position of the ignition point).
