摘　　要：通过深入探讨镁基储氢材料在吸氢过程中的行为,研究了金属氢化物储氢容器在吸氢过程中的关键影响因素。利用COMSOL Multiphysics软件构建了镁基材料储氢容器的几何模型和数学模型,对吸氢过程的不同阶段进行了系统分析,通过数值模拟揭示了温度和压力的变化对金属氢化物吸氢性能的影响规律。研究结果表明,适宜的初始温度与入口压力有助于提升吸氢性能,初始温度为583 K时吸氢性能较好,入口压力在2.5 MPa时吸氢性能较好。此外,研究还通过网格独立性验证和模型验证,确保了模拟结果的准确性。通过对不同参数的分析,不仅深化了对镁基储氢材料吸氢行为的理解,对优化镁基储氢材料在储氢容器中的储氢性能提供了参考,也为储氢系统的设计优化提供了理论支持。The behavior of magnesium-based hydrogen storage materials during the hydrogen absorption process was explored,and the critical factors affecting metal hydride hydrogen storage containers during hydrogen absorption were examined.A geometric and mathematical model of a magnesium-based hydrogen storage container was developed using COMSOL Multiphysics software.A systematic analysis of different stages of the hydrogen absorption process was conducted,and numerical simulations were performed to reveal the influence of temperature and pressure variations on the hydrogen absorption performance of metal hydrides.The results indicated that appropriate initial temperature and inlet pressure contributed to enhanced hydrogen absorption performance,with optimal hydrogen absorption observed at an initial temperature of 583 K and an inlet pressure of 2.5 MPa.Additionally,the study ensured the accuracy of the simulation results through grid independence verification and model validation.The analysis of different parameters not only deepened the understanding of the hydrogen absorption behavior of magnesium-based hydrogen storage materials,but also provided insights for optimizing their hydrogen storage performance in storage containers.Furthermore,this study offered theoretical support for the design and optimization of hydrogen storage systems.
