چکیده انگلیسی
Ignition delay times of dimethyl carbonate were measured in a shock tube for the first time at T = 1100-1600 K, p = 0.12-1.0 MPa, fuel concentration = 0.5-2.0%, and ϕ = 0.5-2.0. A modified chemical kinetic model was developed and can well predict ignition delay times and activation energies. Further validation of the proposed kinetic model was made on the basis of the opposed flow diffusion flame data. Reasonable agreements were also achieved under the literature data. Reaction pathway analysis shows that at high temperature the DMC molecule is primarily consumed through the H-abstractions but not fuel unimolecular decompositions. Sensitivity analysis provides some key fuel-species reactions for DMC high temperature ignition.
