需要氨的直接燃烧来减少化石燃料的消耗。然而，氨具有极低的层流燃烧速度。因此，有必要提高氨的燃烧速度。本文研究了非平衡等离子体对氨燃烧问题的影响。为了减少时间尺度差异带来的计算量，模拟分两个阶段进行：一段是混合物上的非平衡等离子体放电，一段是燃烧。利用CHEMKIN-Ⅱ软件包中的SENKIN程序，将流动反应器中的等离子体放电反应模拟为理想搅拌反应器（PSR）。其次，层流火焰位于下游的流动反应器使用的PREMIX代码在CHEMKIN-II包模拟。从模拟结果来看，随着电场施加时间的增加，未燃气体中氨的分解量增加，层流燃烧速度变得相当快。而且，它……
Direct burning of ammonia is required to reduce the consumption of fossil fuels. However, ammonia has an exceedingly low laminar burning velocity. Therefore, it is necessary to improve the burning velocity of ammonia. In this study, the effect of nonequilibrium plasma on the problems of ammonia combustion is investigated. To reduce a calculation load from the difference of time scale, simulation is conducted in two stages: a section of nonequilibrium plasma discharge on a mixture and a section of combustion. The reactions of plasma discharge in a flow reactor are simulated as a perfect stirred reactor (PSR) using the SENKIN code in the CHEMKIN-II package. Second, the laminar flame located downstream of the flow reactor is simulated using the PREMIX code in the CHEMKIN-II package. From the simulation results, as the time of the application of the electric field increases, the amount of decomposed ammonia in the unburned gas increases and the laminar burning velocity becomes considerably fast. Moreover, it ...
