摘　　要：采用计算流体力学方法对非能动氢复合器(PAR)稳态消氢过程进行了模拟,分析了催化板间距变化对消氢性能的影响。在所分析催化板间距变化范围内,随着催化板间距增加(PAR宽度相应增加),PAR消氢速率和PAR进口混合气流量均增大,而PAR消氢效率减小,催化板表面平均温度和PAR出口平均温度先增大,后减小。当催化板间距增加到某一定值时,PAR消氢速率增大趋势转变为线性变化,PAR消氢效率、催化板表面平均温度和PAR出口平均温度则转变为线性减小,而PAR进口混合气流量始终保持线性增大。Steady hydrogen depletion processes of passive autocatalytic recombiners （PAR） were simulated using computational fluid dynamics method and the effect of the interval between catalyst plates on the hydrogen depletion performance was analyzed. In the range of analyzed intervals between catalyst plates, hydrogen depletion rate of PAR and inlet gas mixture flowrate of PAR increased, while hydrogen depletion efficiency of PAR decreased, with the interval increase between catalyst plates. Both of the average temperatures of catalyst plate surface and PAR outlet increased firstly then decreased. When the interval between catalyst plates was increased to a certain value, the increasing trend of hydrogen deletion rate of PAR became linear, and hydrogen depletion efficiency of PAR, average temperature of catalyst plate surface and average temperature of PAR outlet changed to linear decrease, while inlet gas mixture flowrate of PAR kept linear increase all along.
