Abstract
An experimental and computational study of methane pyrolysis and oxidation and formation of soot particles in reflected shock waves has been performed using a previously proposed unified kinetic model. The model makes it possible to describe the consumption of initial methane molecules and formation of products during pyrolysis and oxidation of various methane–oxygen–argon mixtures. The results of experiments in shock tubes of various designs, equipped with different means of detection of the initial components and secondary products, were compared with the predictions of kinetic simulations. In general, the kinetic model demonstrated good predictive power.
