Abstract
Ignition delay times were obtained behind the reflected shock waves for the diluted stoichiometric methane/hydrogen blends with hydrogen fractions of 20%, 60%, and 80%. Test temperatures from 980 K to 1820 K and pressures from 0.5 to 2.0 MPa. Results show that increase in hydrogen fraction significantly promotes the ignition of fuel blends due to high activity of hydrogen. Pressure-dependence of auto-ignition for methane/hydrogen was observed in three ignition regimes (methane chemistry dominating ignition, combined chemistry of methane and hydrogen dominating ignition and hydrogen chemistry dominating ignition). An explanation of the interaction between chemistries of methane and hydrogen were given by fuel flux analysis using NUIG Mech C5-49.
