Modeling on ignition delay time of dimethyl carbonate

Ignition delay time of dimethyl carbonate was measured in a shock tube at T=1, 100-1, 600, K, p=0.12-1.0, MPa, φ =0.5-2.0, and 0.5%-2.0% fuel concentration. The only DMC model of Glaude model has been validated by ignition delay time and it gives the higher prediction than the measured data. A chemical kinetic model(Present model)was developed and it can well predict the ignition delay time of dimethyl carbonate. Further validation of the modified DMC model was made on the basis of the opposed flow diffusion flame data in literatures. Reaction pathway analysis shows that DMC molecule is primarily consumed through the H-abstractions. Sensitivity analysis indicates several key fuel-species reactions affect the DMC ignition delay time.
