Abstract

In order to investigate the characteristics of correlated dynamic adaptive chemistry(CO-DAC)in turbulent combustion,a LES for nonpremixed jet flame Sandia Flame-D was conducted using GRI-Mech 3.0 detailed chemical mechanism with CO-DAC reduction method.The comparison between simulated results and experimental data demonstrates that using detailed chemical mechanism and CO-DAC reduction can efficiently capture the instantaneous structure of turbulent flame,adaptively reduce the number of computations for chemical reaction and speed up the simulation,accurately simulate velocity and temperature profiles,and accurately simulate important immediate species and radicals profiles based on the characteristics of the combustion field.
