The present contribution presents the results on the modelling / computational work and theoretical
analysis performed within WP5 “Combustion” of the PRESLHY project. Separate phenomena of
cryogenic hydrogen accident scenario, relevant to combustion have been analyzed and numerically
simulated: – jet fire behaviour and heat radiation; – pressure peaking phenomena (PPP); – maximum
combustion pressure under cryogenic high pressure hydrogen release; – BLEVE. The models, numerical
simulations and results of the analysis were validated against experiments performed within PRESLHY
project as well as known experiments from the literature. The extension of the numerical simulations
and analytical results to real accident scenarios with respect to safety distances evaluation was provided
then as engineering tools guideline.
