摘要

摘要针对亚音速气流中带有催化纳米粒子的激光热化学非稳态问题，开发了一种对物理过程进行分割的有限体积算法。模拟了在激光辐射下加热管道中的两相流动以及甲烷非氧化转化的自由基动力学。结果表明，管道出口处的甲烷转化率超过 60%，主要形成乙烯和氢气。

Mathematical Modeling of Nonstationary Problems Related to Laser Thermochemistry of Methane in the Presence of Catalytic Nanoparticles

A finite-volume algorithm with splitting over physical processes is developed to model nonstationary problems of laser thermochemistry with catalytic nanoparticles in subsonic gas flows. Two-phase flows in a heated pipe with laser radiation and radical kinetics of nonoxidative methane conversion are simulated. It is shown that the conversion of methane at the outlet of the pipe is more than 60% with predominant formation of ethylene and hydrogen.
