Global reduced mechanisms for methane and hydrogen combustion with nitric oxide formation constructed with CSP data

摘要: Reduced mechanisms for methane-air and hydrogen-air combustion including NO formation have been constructed with the computational singular perturbation (CSP) method using fully automated algorithm described by Massias et al. The analysis was performed on solutions of unstrained adiabatic premixed flames detailed chemical kinetics GRI 2.11 methane a 71-reaction mechanism hydrogen x formation. A 10-step reduced has which reproduces accurately laminar burning velocities, flame temperatures mass fraction distributions major species whole flammability range. Many steady-state are also predicted satisfactorily. This is an improvement over seven-step set al, especially rich flames, because use HCNO, HCN C2H2 as results in better calculation prompt NO. present may thus be applicable to diffusion flames. five-step me...
