Abstract

Numerical simulations of ethanol combustion with a reduced kinetic mechanism were performed for one-dimensional premixed laminar flames and two-dimensional Bunsen flames at various equivalence ratios and pressures. A reduced kinetic mechanism was generated based on the quasi-steady-state assumption (QSSA) using the Computational Singular Perturbation (CSP) method and its validity and range of application were tested. Calculation results, i.e., temperature, chemical species profiles and laminar burning velocity of the detailed mechanism and reduced kinetic mechanism for both 1-D and 2-D simulations were in good agreement. Calculation cost with the reduced mechanism was considerably reduced compared to that using the detailed mechanism.
