DNS of EGR-type combustion in Mild condition

Yuki Minamoto (Energy)

Direct numerical simulation (DNS) of exhaust gas recirculation (EGR)-type combustion operated in moderate and intense low-oxygen dilution (Mild) combustion condition have been carried out to study the flame structure and its physics. Simulated flame is then investigated from several aspects to study the effect of dilution on the structure of this flame front. The results suggest that the flame can be modelled with flamelet approaches, although the contribution of flame-flame interaction to mean reaction rate should be taken into account.
