Lossless storage and transportation law of 250m3 horizontal liquid hydrogen storage tank

In this paper, the effects of initial filling rate and heat flux density on natural convection inside liquid hydrogen storage tank variation laws temperature pressure are studied. The study found that optimal 250m3 was 86%. When is in range 35% to 95%, change has a greater impact self-pressurization phenomenon than rate. lower 35%, rises sharply, great influence phenomenon. high make rise faster during recovery period. begins evaporate large quantities, low increase faster. By comparing three thermodynamic models with simulation results, it deviation 250 m3 86% within 20% calculated by three-zone model, which closest results. surface evaporation model at reached 76% 88.3%, respectively, most affected calculation
