Development of a compact and robust Polyoxymethylene Dimethyl Ether 3 reaction mechanism for internal combustion engines

With high oxygen content, Polyoxymethylene Dimethyl Ether 3 (PODE3) is a potential fuel additive to reduce soot emissions. However, reaction mechanisms to describe PODE3 combustion are not yet compact enough for 3-D numerical simulations. Therefore, the current work aims to develop a small yet reliable PODE3 reaction mechanism. Based on sensitivity analysis, the major reaction pathway is identified to construct the PODE3 sub-mechanism....
