摘　　要：采用计算流体力学方法对具有相同尺寸的非能动氢复合器稳态消氢过程进行了模拟,分析了催化板数量改变对复合器消氢性能的影响。在所分析催化板数量范围内,随着催化板数量增加,消氢速率和消氢效率先线性增大,再呈抛物线变化;催化板表面温度先增大再有所减小。氢气局部点火风险随着催化板数量增加而增大。Steady hydrogen depletion processes of passive autocatalytic recombiners with a same size were simulated using computational fluid dynamics method and the effects of catalyst plate number on the hydrogen depletion performance were analyzed. In the range of analyzed catalyst plates number, hydrogen depletion rate and efficiency increased first, and then varied in shape of parabolas, and the surface temperatures of catalyst plates increased first, and then decreased with certain extents. The local hydrogen ignition risk was enlarged with the catalyst plate number.
