On the Possibility of Promoting a Detonation Condensation Wave in Acetylene with Methane Additions

A numerical analysis of the recently discovered promoting of the growth of condensed carbon nanoparticles during the thermal decomposition of acetylene in the presence of methane additives has been performed. Calculations carried out using the modern kinetic mechanism, describing the growth of carbon nanoparticles during hydrocarbon pyrolysis and combustion, have confirmed a significant acceleration of the growth of polyaromatic hydrocarbons and nanoparticles, as well as temperature and pressure during shock wave pyrolysis of acetylene with the addition of 10% methane. The results indicate a possible decrease in threshold pressure and acceleration of the development of acetylene detonation in the presence of methane additions.
