Numerical Investigation of the Effect of Hydrogen Addition on Methane Flame Velocity and Pollutant Emissions Using Several Detailed Reaction Mechanisms

This research’s basic objective is the study of hydrogen addition effects on pollutant emissions like CO and CO2 and on the laminar velocity of a methane flame considering a detailed chemical kinetics. This numerical study was performed using the calculation code of the gas phase chemical kinetics ChemKin4.0. To do this, the internal combustion engine (ICE) model was used to simulate the CO and CO2 emissions and the flame speed calculation (FSC) model for calculating the laminar velocity for various detailed reaction mechanisms and under different mixing conditions of CH4 + H2 and at equivalence ratio values ranging from 0.6 to 1.4. Results were compared with various experimental data from the literature and very good concordance was observed for several of the detailed mechanisms. © 2018, Springer Nature Switzerland AG.
