Abstract
The effects of the addition of small amounts of molecular and atomic hydrogen/oxygen on laminar burning velocity, pollutant concentrations, and adiabatic flame temperatures of premixed, laminar, freely propagating iso-octane flames are investigated using CHEMKIN kinetic simulation package and a chemical kinetic mechanism at different equivalence ratios. It is shown that hydrogen/oxygen additives increase the laminar burning velocities. Increased hydroxyl (OH) concentrations resulted in reduced carbon monoxide (CO) emissions in every stoichiometric ratios investigated. Additives also increased the adiabatic flame temperature of iso-octane/air combustion, thereby causing increased NOx concentrations for all additives at all stoichiometries.
