Kinetic modeling of the ignition dlays in monomethylhydrazine/oxygen/argon mixtures

摘要

Ignition delay times for monomethylhydrazine (MMH or CH_3NHNH_2)/O_2/Ar gaseous mixtures have been modeled by a reaction scheme containing 70 species and 373 equilibrated elementary reactions.For many reactions,the rate ocnstants had to be estimated or adjusted because rate ocnstants are available for only a few reactions.the basis for a comparison with reality is mearueemnts of ignition delay times behind reflected shock waves performed over a range of temrpatures,pressrues,and ocmposition.
