| 摘 要： | 通过改变指前因子和活化能系数,构建氢气燃烧单步反应机理,利用构建的单步机理开展严重事故下氢气燃烧计算分析,将计算结果与试验数据进行对比分析,同时利用机理开展不同氢气浓度条件下氢气燃烧数值计算。结果表明:单步机理在氢气火焰传播速度方面计算值与试验值符合很好,修正后的氢气燃烧单步机理可用于核电厂氢气燃烧计算分析。

| Abstract: | Changing the pre-exponential factor and the activation energy coefficient, the single-step reaction mechanism for hydrogen combustion was established, and the calculation and analysis of hydrogen combustion have been conducted by this mechanism. The results from the calculation and the experiment were compared, and the calculations of hydrogen combustion were processed in different hydrogen concentration by the single-step reaction mechanism. The results showed that the calculations and experimental flame propagation were conformable, and the modified single-step reaction mechanism for hydrogen combustion can be used to calculate and analyze the hydrogen combustion in nuclear power plants. |
