Abstract
En 中文
Double-walled vacuum insulated storage vessels incorporate a vacuum layer between the outer and inner vessels to provide thermal insulation, and support structures of minimal cross-sectional area to limit heat penetration and suppress boil-off gas generation within the inner vessel. However, sudden braking during vehicle transportation can introduce external dynamic loads that induce sloshing of the free surface of the cryogenic fluid, potentially damaging the internal support structures. In this study, the sloshing behavior of liquid nitrogen at a 50% filling ratio within a double-walled vacuum insulated storage vessel was analyzed under dynamic loading conditions, simulating sudden braking. The influence of baffles installed inside the inner vessel on sloshing reduction was evaluated, with a case study investigating the effects of baffle's location and height on the structural integrity of the support structures.
