Two-dimensional cellular structure of a kinetically unstable detonation front

Based on previously published results on the detonation of gaseous and liquid explosives, an explanation is given to the formation of the two-dimensional cellular structure of the detonation front of some gas mixtures undergoing a two-step exothermic transformation at the wave front and suggestions are proposed for the mechanism of development of the two-dimensional cellular structure in the case of detonation transformation of gas mixtures with one-step chemical kinetics. __________ Translated from Fizika Goreniya i Vzryva, Vol. 44, No. 4, pp. 80–86, July–August, 2008.
