Abstract:
A kinetic model for the ignition and combustion of mixtures of propane and $n$-butane in the air has been developed. The model contains 348 reactions involving 72 species and includes both a high and low-temperature mechanism of propane and $n$-butane oxidation. The kinetic model was tested against experimental data on the ignition delay time and laminar flame speed. The model provides a good fit to experimental data on propane ignition and the laminar flame speed in propane-air mixtures, ignition of $n$-butane under different initial conditions ($T_0=670-1550$ K, $p_0=1-30$ атм, $\phi=0.3-2.0$), laminar flame speed in mixtures of $n$-butane with air at $T_0=298$ K,
$p_0=1$ atm, and various stoichiometric ratios $\phi=0.67\div1.5$), as well as on the ignition of stoichiometric $\mathrm{C}_3\mathrm{H}_8/\mathrm{C}_4\mathrm{H}_{10}/\mathrm{N}_2/\mathrm{Ar}$ mixtures with different relations $\mathrm{C}_3\mathrm{H}_8/\mathrm{C}_4\mathrm{H}_{10}$ at $T_0=710-910$ K and $p_0=17.8$ atm. The developed kinetic mechanism was used to perform a demonstration numerical simulation of combustion of propane-butane fuel in a homogeneous combustion chamber
