“…In their review, they note that Pritchard and Rattigan [25] identified "the consequences of an accidental spillage or leak of liquid hydrogen are poorly understood, particularly the initial stages of pool spread and vaporization." The limited experimental data available in the scientific literature [26][27][28][29][30][31][32][33][34][35] is generally of insufficient quality for model development/validation due to poor control of the boundary conditions or low measurement fidelity. Accordingly, there is the risk that the use of improperly validated models to establish safety envelopes could be detrimental to the emergence of hydrogen as a transportation fuel.…”

“…For these experiments, controlled ground-level spills from storage containers as large as 5. [28], with pool spreading rates and gas-cloud concentrations measured at discrete locations. Like their NASA counterparts, BAM researchers concluded that ground heat transfer effects and fast dissipation rates helped limit the size and duration of LH2 pools and flammable clouds.…”

“…There have been several LH 2 spill experiments conducted by NASA, BAM (Federal Institute for Materials Research and Testing, Germany), and HSL (Health and Safety Laboratory, UK) . The release rates in the tests of BAM and HSL were low (5–6 L/s and ~60 L/min), and those in the NASA tests were large (~5.7 m 3 released in 38 s).…”

“…Περίπου μια δεκαετία αργότερα διεξήχθη και δεύτερη σειρά πειραμάτων μεγάλης κλίμακας με διασπορά υγρού υδρογόνου από το BAM (Schmidtchen and Marinescu-Pasoi, 1994), στα πλαίσια του προγράμματος EQHHPP (Gretz et al, 1992) , (Qi et al, 2010) K είναι οι τυρβώδεις συντελεστές διάχυσης στην y και z κατεύθυνση, αντίστοιχα. Η τυρβώδης διάχυση στην x κατεύθυνση αμελείται, διότι θεωρείται ότι η συνεισφορά της είναι αρκετά μικρότερη από τη συνεισφορά της συναγωγής λόγω του ανέμου.…”

“…Οι (Schmidt et al, 1999) και ο (Statharas et al, 2000) χρησιμοποίησαν το ομογενές μοντέλο για να προσομοιώσουν τη σειρά πειραμάτων BAM (Schmidtchen and Marinescu-Pasoi, 1994) με το CFD κώδικα Fluent 4 και τον ADREA-HF, αντίστοιχα. Οι (Schmidt et al, 1999) βρήκαν ικανοποιητική συμφωνία με το πείραμα, αλλά επισήμαναν ότι τα αποτελέσματα χρήζουν βελτίωσης.…”
