摘要

本研究针对金属氢化物储氢过程中传热受限的问题，通过数值模拟研究了叶脉仿生翅片结构及其操作参数对储氢性能的影响。在翅片体积相同的条件下，设计了3种不同分形复杂度的结构(Ⅰ型、Ⅱ型、Ⅲ型)，系统分析了不同结构以及入口压力、传热流体流速与温度对反应过程的影响。结果表明，Ⅲ型翅片通过增加有效传热面积和强化径向热扩散，显著提升了反应器内温度分布的均匀性，形成了稳定的径向温度梯度。在相同工况下，其吸氢完成时间为670 s，较Ⅰ型翅片缩短38.5%，验证了结构优化对传热与反应动力学的协同增强作用。参数分析显示：入口压力升至1.0 MPa前，反应加速显著，超过后促进作用趋于稳定；传热流体流速超过1.0 m/s后，传热逐渐由内部热传导主导，继续提升流速，性能提升效果有限；传热流体温度降至296.15 K以下后性能提升趋缓，考虑能耗因素，建议在近室温条件下运行。综上所述，采用多级分支叶脉仿生翅片结构，并结合适宜的操作参数，可有效协同优化金属氢化物储氢反应器的传热与反应性能，本研究为其工程应用提供理论依据。

Abstract

To investigate heat transfer limitations in metal hydride hydrogen storage systems

numerical simulations were conducted on leaf-vein-inspired fin configurations and their operating parameters. Three fin structures with graded fractal complexity (Type Ⅰ

Ⅱ

and Ⅲ) were designed with identical fin volumes. The effects of fin geometry

inlet hydrogen pressure

heat transfer fluid velocity

and heat transfer fluid temperature on the absorption process were systematically analyzed. The results indicate that the Type Ⅲ fin improves temperature uniformity within the reaction bed by increasing the effective heat transfer area and enhancing radial thermal diffusion

thereby establishing a stable radial temperature gradient. Under identical operating conditions

the Type Ⅲ fin reduced the hydrogen absorption time to 670 s

which is 38.5% shorter than that of the Type Ⅰ fin. This confirms that topological fin optimization synergistically enhances both heat transfer and reaction kinetics. Parameter analysis reveals the following trends: hydrogen absorption accelerates with increasing inlet pressure up to 1.0 MPa

beyond which further pressure increases yield diminishing returns; heat transfer fluid velocities above 1 m/s provide limited additional benefit

as heat transfer becomes dominated by internal conduction within the metal hydride bed; although lower heat transfer fluid temperatures enhance the thermal driving force

performance gains diminish below 296.15 K. Therefore

near-ambient temperature operation is recommended to balance absorption efficiency and cooling energy consumption. In summary

a multibranch leaf-vein-inspired fin structure combined with appropriately selected operating parameters can effectively improve heat management and hydrogen absorption performance in metal hydride reactors

providing a practical basis for the design and operation of efficient hydrogen storage systems.
