Nonclassical regimes of wave diffraction in combustible mixtures

Abstract

Experimental and numerical results of investigating the diffraction of combustion and detonation waves, including the diffraction in unsteady deflagration-to-detonation transition regimes, are presented.

Effect of the bifurcating duct on the gas explosion propagation characteristics

“…Ibrahim and Masri [3] experimentally studied the baffle size effect, the blockage ratio, and the relief pressure on the deflagration pressure of the premixed flame; they found that the shape and the flame velocity varied with the baffle and the blockage ratio, the deflagration pressure increased with the relief pressure, but the extent of this increase depended on the baffle shape. Vasil'ev et al [4,5] studied the propagation of a detonation wave in channels with perforated walls and the diffraction of combustion and detonation waves, including the diffraction in unsteady deflagration-todetonation transition regimes. Lin et al [6,7] Xie et al [8] found that the baffle and diaphragm in the duct can induce the turbulence and make the flame velocity increase obviously.…”
