Validation of CFD modelling of LH2 spread and evaporation against large-scale spill experiments

In the present work, the liquid hydrogen spill experiments carried out by NASA are simulated with the pool model. The large-scale NASA experiments [8], [9] consisted of 7 releases of liquefied hydrogen at White Sand, New Mexico. The release test 6 is used. During these experiments, cloud concentrations were measured at several distances downwind of the spill point. With the new pool model feature, the FLACS tool is shown to be an efficient and accurate tool for the investigation of complex and realistic accidental release scenarios of cryogenic liquids.
