磁场对瓦斯爆炸及其传播的影响
Effects of magnetic field on methane explosion and its propagation
摘要
Abstract
To master the effect of the magnetic fields produced by the giant mechanical and electrical e-quipments in coal mines on methane explosion, experimental investigations were conducted to explore the influences of the magnetic fields on explosion wave pressure and flame propagation velocity of methane explosion. And theoretical analysis was carried out to discuss the effect of the magnetic fields on heat transportation, mass transportation and reaction process of methane explosion and its propagation. It shows that the magnetic field can enhance methane explosion intensity and increase flame propagation velocity, explosion pressure. The more the magnetic field intensity, the more markedly the magnetic field affects methane explosion. The magnetic fields can increase turbulence by increasing mass transfer action, heat transfer action, convection effects, diffusion coefficient and entropy of the reaction system, so the magnetic fields can increase flame combustion velocity, flame propagation velocity, release more energy and increase shock wave energy, and then promote the methane explosion and its propagation.关键词
