摘要(Abstract)：

为探究固态储氢反应器内的热质传递过程，建立了反应器的二维数值计算模型，分析了反应器内固态储氢材料的径向反应分率分布特性，以及储氢材料床层厚度与换热管径对饱和半径的影响规律，进而开展了换热管束优化布置研究。结果表明：换热管存在对应的最大饱和半径，且随管径增加而增大；当管半径为1.00～6.00 mm的单管布置时，最大饱和半径分别为2.60、3.30、3.50、3.70、3.80、3.90 mm，其中半径为1.00、2.00、3.00 mm的换热管体积分数较小，分别为7.72%、14.24%、21.30%，当这3种换热管以管束布置时，较优的管间床层厚度分别为4.86、6.09、6.38 mm；此外，增设换热管束可有效改善反应器内反应死区的储氢性能。在半径2.00 mm换热管束的反应器内，与未增设换热管束相比，在反应死区增设12根半径1.00 mm换热管后储氢时间减少了40.00%，为267 s，而换热管束体积分数仅增加了1.92%，储氢量仅减少2.17%。该研究成果可为固态储氢反应器的优化设计奠定基础，并为后续的工程应用提供指导。
