This paper reports the numerical simulation of the sudden hydrogen release from a cryogenic pressure vessel due to a broken tube where hydrogen vents into the vacuum jacket. Real gas effects are considered and the specific “vessel within vessel” geometry of cryogenic vessels. For practical reasons, this study focuses on hydrogen release from 34.5 MPa, with initial temperatures of 62 K and 300 K. The high pressure vessel internal volume is 151 L. Pressure versus time graphs indicate that the vacuum jacket resist the pressure build up until reaching the rupture disc setting to finally release into the atmosphere, and a comparative of this result with the ASME Code burst pressure calculation is presented.
