Mathematical modeling of nonstationary problems of methane's laser thermochemistry in the presence of catalytic nanoparticles

The article states the computational algorithm based on the finite volume method with splitting by physical processes for modeling non-stationary 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 non-oxidative methane conversion are simulated. It is shown that the conversion of methane is more than 60 % with the predominant formation of ethylene and hydrogen at the outlet of the pipe.
