摘要
Advanced insulation systems are critical for efficient liquid hydrogen storage and transportation. To enhance thermal insulation performance, this study proposes a thermal insulation system integrating vapor-cooled shield (VCS) driven by liquid nitrogen boil-off gas (BOG) with variable density multilayer insulation (VDMLI). Two VCS operation modes, Top-down and Bottom-up, are designed based on the BOG flow direction. A thermodynamic model for the insulation system and a self-pressurization model for the storage tank are developed to optimize the VCS position under constant-temperature boundary conditions, identifying the 23rd VDMLI layer as optimal. On this basis, the impact of VCS operation modes on tank self-pressurization and self-evaporation behaviors is further analyzed. The results indicated that liquid nitrogen BOG-driven VCS significantly improves thermal insulation, reducing heat flux density to 0.137 W/m2—59.3% lower than that of VDMLI alone (0.337 W/m2). Moreover, the Top-down mode exhibits superior thermal insulation performance across various scenarios due to its prioritization of cold shielding in the vapor zone. These findings provide theoretical and technical guidance for optimizing liquid hydrogen tank insulation systems. © 2025 Hydrogen Energy Publications LLC
