甲烷掺氢诱导末端混合气电离一维机理模型研究
One-dimensional mechanism model of end-gas ionization induced by Hydrogen-enriched compressed natural gas
天然气由于有较高热效率和较少的污染排放，被普遍认为是一种汽油的替代燃料。但其燃烧会产生排放大量的 CO2，难以满足低碳要求。氢气是无污染燃烧的理想燃料，然而氢气的体积热值较低，大规模使用氢气的技术并不成熟。在天然气中掺杂氢气将成为化石能源利用向氢能利用过渡的最可行的解决方案之一，本文为了更准确的和从更本质的角度研究碳氢火焰中离子电流的形成机理，基于MATLAB平台开发了一维火焰/电磁多物理场耦合的瞬态反应流求解器，对不同掺氢比下甲烷末端混合气燃烧的过程进行了仿真。
Natural gas is widely regarded as an alternative fuel to gasoline because of its high thermal efficiency and fewer polluting emissions. But its combustion will produce a lot of CO2 emissions, it is difficult to meet the low-carbon requirements. Hydrogen is an ideal fuel for pollution-free combustion, but the volume calorific value of hydrogen is low, and the technology for large-scale use of hydrogen is not mature. Doping hydrogen in natural gas will b…查看全部>>
