TLDR
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.About:

Xinyu Chang,Chunhua Bai +1 more
TL;DR: In this paper , the influence of gas jets on explosion behavior of hydrogen-air mixtures with various hydrogen concentrations (from 10% to 70%) at different initial pressures (i.e., 50kPa, 100 kPa, 150 kPa and 200 kPa) was investigated.

Application of large eddy simulation in methane-air explosion prediction using thickening flame approach
TL;DR: In this article , a large eddy simulation (LES) is carried out to investigate the stoichiometric methane-air explosion through using thickening flame model and the power-law model is used to evaluate the efficiency factor and a reduced two-step combustion mechanism is considered for the methane air combustion.

Explosion behavior of non-uniform methane/air mixture in an obstructed duct with different blockage ratios
TL;DR: In this paper , an experimental investigation on explosion behavior of non-uniform methane/air explosion in obstructed duct with different blockage ratios was conducted, and the results showed that the vertical concentration gradient of methane upstream along the obstacle increases with blockage ratio.

Nonlinear analysis of hydrodynamic instability in laminar flames—I. Derivation of basic equations
TL;DR: In this paper, an asymptotic nonlinear integrodifferential equation for spontaneous instability of the plane front of a laminar flame is derived, and it is shown that in all cases spontaneous instability implies an increase in its propagation velocity.
