Abstract

In this study, the effects of the addition of small amounts of water electrolysis products on laminar premixed iso-octane flames are investigated using kinetic simulation. The CHEMKIN kinetic simulation package, incorporating a recently developed chemical kinetic mechanism for iso-octane combustion, is used. Burning velocity predictions using the iso-octane mechanism that is developed at RWTH-Aachen are compared with recent experimental data to test for its accuracy on premixed, laminar, adiabatic, freely propagating flame conditions. The mechanism is then used to predict the combustion properties of iso-octane/air systems with H2 and O2 additions at different percentages and equivalence ratios. Carbon monoxide (CO) and hydroxyl (OH) concentrations, adiabatic flame temperatures, and burning velocities of iso-octane/air combustion are compared with the values obtained with the addition of H2 and O2. It is found that electrolysis products addition to iso-octane combustion is helpful in terms of burning velocity enhancements and CO reductions, but the temperature profiles showed no significant differences.
