Influence of hydrogen bromide on a laminar burning velocity of the hydrogen and methane mixtures with nitrous oxide and nitrogen-oxygen compositions
An influence of hydrogen bromide on the laminar burning velocity of hydrogen and methane mixtures with air, nitrous oxide and nitrogen-oxygen composition with content of 33% O2 (vol.) by numerical modeling of the flat flame spreading, taking into detailed account the chemical kinetics and transport process, has been studied. It was found that hydrogen bromide at burning with nitrous oxide has less fire-retardant efficiency than at burning of air mixtures and mixtures, in which oxidizer was nitrogenoxygen composition with oxygen content of 33% O2 (vol.). Qualitative interpretation of the obtained results based on the analysis of the chemical processes during the combustion of the mentioned above mixtures has been carried out.
