This Review examines the gas-phase oxidations of hydrogen and other fuels (ammonia, hydrazine, hydrocarbons) with nitrous oxide, running as self-ignitions, deflagrations, or detonations. Taking into account the main feature of nitrous oxide, i.e., its ability to decompose exothermally, this Review summarizes also the conditions determining an explosive evolution of N 2 O decomposition, and the characteristic parameters of this process, as self-ignition or after ignition by local energy sources. For fuel− nitrous oxide explosive combustion, this Review is focused on conditions where the explosive combustion takes place (flammability limits, minimum ignition energy) or it is quenched (quenching distance, Maximum Experimental Safe Gap) and on the characteristic properties of explosion development and propagation. These properties are separately examined for deflagrations and detonations. The DDT (Deflagration-to-Detonation) process is also taken into account, because it occurs in most technical applications of fuel−N 2 O combustion in enclosures. This Review is completed by a discussion of processes where nitrous oxide is promoter of fuel−oxygen or fuel−air explosive combustion.

A computational study was conducted on the addition of nitrogen (0–60 vol%) to stoichiometric hydrogen–nitrous oxide flames at various initial pressures (1–10 bar) and temperatures (300–500 K), with a special emphasis on NO, which is a major pollutant that is generated by these flames. The detailed kinetic modeling of H2–N2O–N2 flames, which was performed using the GRI 3.0 mechanism, produced the structure of the H2–N2O–N2 flames for the temperature and mass fraction profiles of 53 species, which participated in 325 elementary reactions. The NO profiles that were computed by the detailed kinetic modeling followed the trend of experimental NO profiles that have been reported in the literature for laminar premixed flames at sub-atmospheric pressures. For the examined H2–N2O–N2 flames, an increase in initial pressure resulted in a significant reduction in the NO mass fraction of the burned gas. The increase in initial temperature was also accompanied by an increase in the mass fractions of the generated NO, as well as the flame temperature.
