Evaluation of detonation parameters for hydrogen-methane- air mixtures in pipelines transport
The authors report on a computational study of the fundamental detonation parameters of stoichiometric hydrogen-methane-air mixtures based on Chapman-Jouguet theory, ZND model and detonation wave cell size calculations. Methane-hydrogen mixture is used at different combustion devices like spark ignited engines, gas turbines, different kind of burners with premixed and diffusion flames. A series of calculations on detonation parameters of stoichiometric hydrogen-methane-air mixtures were made with different H2 contents in the mixture, from 10% up to 100% of hydrogen. The effects of the initial composition of the mixtures as well as initial pressure on the detonation velocity and cell size were investigated. Hydrogen addition to existing natural gas pipelines results in increase of safety rather than pure hydrogen transport, especially in the context of detonation parameters. Furthermore, such mixtures can make hydrogen as an energy carrier all over the world where due to storage and transport problems in large industrial scale it seems to be a long future.
