Developed a Reduced Kinetic Model for HCCI Combustion of DME and Coupled with CFD Model

The paper presented a reduced dimethyl ether (DME) combustion model for Homogeneous Charge Compression Ignition (HCCI) using the sensitivity analysis and rate of production analysis approaches. This model consists of 28 species and 32 reactions. It shows great agreement with the detailed model in terms of ignition timing and species concentrations. Spatially three-dimensional calculations were conducted to couple with reduced model using the FLUENT code. The results show that the computation times are acceptable and the accuracy does not drop.
