In scramjet engines, ignition must take place within a residence time on the order of milliseconds. this study, secure conditions for specified n-octane pyrolysis fuel components used in autoignition or forced-ignition by plasma jet torch high-speed flow were numerically investigated. First, delay combustor and cavity flame-holder was estimated using chemical reaction analysis. Three (n-C8H18, ...

We propose a new single-step mechanism for the combustion of arbitrary hydrocarbons and alcohols. Unlike most models, no tabulation is required, as method builds upon analytical description thermochemical equilibrium fuel-oxidizer mixtures including dihydrogen carbon monoxide – two species usually discarded in one-step descriptions yielding correct adiabatic temperature. The chemistry includes ...
