Abstract

A computational study is performed to investigate the effects of CO 2 addition on the ignition of premixed H 2/air mixtures with detailed chemistry for adaptive simulation of unsteady reactive flow. The changes of the minimum ignition energies (MIE) with the dilution ratio for different stoichiometric H 2/air/CO 2 mixtures are obtained. Radiation sensitivity and reaction sensitivity are introduced to examine the radiation and kinetic effects on the MIE. It is found that the radiation and kinetic effects of CO 2 lead to remarkable increase in the MIE only when the dilution ratio is close to the dilution limit.
