TL;DR: In this article, the effects of equivalence ratio, ammonia addition and initial pressure on the flame morphology and explosion pressure are revealed, and the results demonstrate that effects of three factors on explosion hazard are ranked from the most important to the least important as initial pressure, equivalence ratios, and ammonia hydrogen.

TL;DR: In this paper, the effect of ultrafine water mist with phosphorus-containing compounds (PCCs) on the flame in CH4/coal dust explosion is experimentally and numerically investigated.

TL;DR: In this article, the authors evaluated the hydrogen cloud explosion under inert gas atmosphere experimentally and numerically and demonstrated that only under Ar, N 2 and CO 2 atmosphere, the lean and stoichiometric hydrogen flame tends to be unstable.

TL;DR: In this paper, a laminar flame model and turbulent flame model are established to theoretically predict maximum explosion overpressure in advance, and the results demonstrated that the flame acceleration of hydrogen cloud explosion with built-in obstacles is attributed to mutual promotion of flame instabilities and obstacle-induced turbulence.

TL;DR: In this article, the authors performed unconfined explosion experiments under different methane concentrations at 27 m3 scale with internal and external obstacles and found that the flame buoyant effect was more obvious for the rich-fuel flame due to the excess methane accumulation.
