On the origin of the double cellular structure of the detonation in gaseous nitromethane and its mixtures with oxygen

Influence of nitromethane concentration on ignition energy and explosion parameters in gaseous nitromethane/air mixtures

“…Some works have also paid attention to the explosion process of gas-liquid two-phase and gas-liquid-solid three-phase within the pipe with a large length diameter ratio [8]. However, except the cellular structure of the detonation in gaseous nitromethane and its mixtures with oxygen [9,10] and the DDT process of gaseous nitromethane mixtures [11] in slender pipes, there are less research reports following with interest in pure gaseous nitromethane mixtures.…”

“…These dual fuel-oxidizer properties motivate studies of combustion characteristics of nitromethane as a single component as well as in mixtures with other oxidizers. Due to its potential as a monopropellant [6], nitromethane has been extensively studied, focusing on thermal decomposition [7][8][9][10][11][12][13][14][15][16][17], and detonation [18][19][20][21][22]. The combustion chemistry of nitromethane is also of interest from a fundamental research viewpoint since it is the simplest representative for fuel-nitrogen species, and as such can facilitate understanding of the reactions relevant to the mutually sensitized oxidation of hydrocarbons and nitrogen oxides [11].…”

“…An interesting aspect of nitromethane combustion is that experiments and modeling indicate that it proceeds via two or three steps; detonation has been shown to be a two-step process [19][20][21][22]24], a similar pattern is seen in low-pressure flames [25] and in the case of flames of liquid nitromethane three reaction zones have been identified [6].…”

Insights into nitromethane combustion from detailed kinetic modeling – Pyrolysis experiments in jet-stirred and flow reactors

“…Though studies on nitromethane are not new, there are a number of studies on nitromethane detonation [19][20][21] and nitromethane decomposition [22][23][24][25]. None of these studies took into account the detailed kinetic study of CH3NO2 combustion.…”
