TL;DR: In this paper, detonation limits in stoichiometric methane-oxygen mixtures with varying tube inner diameter and initial mixture pressure were investigated, and an alternate length scale at the limits was examined, Ldcs, which is the maximum length from the beginning of the test section after which cellular patterns can no longer be observed.

TL;DR: In this paper, the detonation failure mechanism in CH4-O2 mixtures with diameters of 2.5, 4.5 and 7.5 mm was investigated in macro-and micro-scale channels.

TL;DR: In this paper, the effect of the porous-walled material on the detonation propagation at the near-limit conditions was investigated, and the results showed that, for shorter porouswalled tubes, the impact of the absorbing material was only prominent at critical and sub-critical conditions, but the material has a minor effect on the explosion propagation at supercritical conditions.

TL;DR: In this article, perforated plates with various blockage ratios are seated at the beginning of the detonation propagation to explore the diffractions generated from the plates on the explosion propagation mechanism, and two explosive mixtures of C2H2 + 5N2O and C2 H2 + 2.5O2 + 70% Ar are studied to illustrate the difference in propagation velocity behavior of detonation after it suffers from large-scale diffractions.

TL;DR: In this paper, the velocity fluctuation near the detonation limits for CH4 2H2 3O2 mixture in tubes with a length (Lt) of 2.5 m and diameter (d) of 4-mm, 14-mm and 36-mm was investigated.
