Effect of N2 and CO2 on explosion behavior of hydrogen-air mixtures in non-premixed state

Effect of N2 and CO2 on the Explosion Properties of High Equivalence Ratios of Hydrogen

“…Li et al 39 studied the influence of inert gases on the bursting of hydrogen clouds by experimental and numerical methods and proposed that inert gases destabilize hydrogen-poor and stoichiometric hydrogen flames. Wei et al 40 and Zhang et al 41 studied the effect of N 2 and CO 2 on the suppression of hydrogen flame properties in fixed-volume incendiary bombs and closed channels, respectively, and noted that CO 2 is a superior flame propagation suppressor than Ar and N 2 . Li et al 42 concluded that the thermal diffusion instability of hydrogen-air explosions increases and hydrodynamic instability decreases as the number of CO 2 increases.…”
