摘要: This study has identify useful reduced mechanisms that can be used in computational fluid dynamics (CFD) simulation of the flow field, combustion and emissions gas turbine engine combustors. Reduced lessen cost possess ability to accurately predict overall flame structure, including temperature species as CH4, CO NOx. The S-STEP algorithm which based on singular perturbation method (CSP) is performed for detailed mechanism GRI-3.0. required input: mechanism, a numerical solution problem desired number steps mechanism. In this work, we present 10-Step obtained through algorithm. rate each reaction depends all species, steady-state non-steady state. former are calculated from system algebraic relations with point relaxation Based premixed code calculations, numeric results were 1 atm ≤ Pressure 30 1.4 ф 0.6 basis ten global compared those computed 10-step predicts accuracy similar by full GRI-3.0 both NOx CH4 chemistry.
