TY - JOUR TI - Evaluation of reduced chemical kinetic mechanisms used for modeling mild combustion for natural gas AU - Hamdi Mohamed AU - Benticha Hmaied AU - Sassi Mohammed JN - Thermal Science PY - 2009 VL - 13 IS - 3 SP - 131 EP - 137 PT - Article AB - A numerical and parametric study was performed to evaluate the potential of reduced chemistry mechanisms to model natural gas chemistry including NOx chemistry under mild combustion mode. Two reduced mechanisms, 5-step and 9-step, were tested against the GRI-Mech3.0 by comparing key species, such as NOx, CO2 and CO, and gas temperature predictions in idealized reactors codes under mild combustion conditions. It is thus concluded that the 9-step mechanism appears to be a promising reduced mechanism that can be used in multi-dimensional codes for modeling mild combustion of natural gas.
