Abstract:
Data on the parameters of explosion and detonation of two- and three-fuel mixtures of methane, coal dust, and hydrogen (with oxygen and air) with varied fractions of the fuels are reported. The novelty of the numerical and graphical arrays is due to previously unknown data on the kinetic energy of detonation initiation, characteristic size of detonation cells, detonation velocity, and energy release in detonation waves. The analysis is performed not only for stoichiometric two- and three-fuel systems, but also for rich and lean systems based on the fuels under study.
Keywords:
multi-fuel systems, initiation, critical energy, mine explosions, detonation cells, bifurcation structures, lean and rich mixtures, explosion hazard, environmental science, “carbon footprint” reduction.
