Abstract : Hydrogen-assisted self-ignition of propane-air mixtures in the sequential feed mode was investigated numerically in Pt/Î³-Al2O3 catalytic micro-combustors. The computational results indicate that, the time taken to reach steady state, the hydrogen cut-off time, the propane ignition time and the cumulative propane emissions increased with increasing wall thermal conductivity; the self-ignition characteristics are similar to partially preheating the initial segment of the micro-combustor for low and moderate conductive walls; however, the self-ignition characteristics are close to completely heating the micro-combustor wall for high-conductivity walls. The minimum cumulative amount of hydrogen usage and minimization of startup time are discussed.
