ASSESSING THE COMBUSTION BEHAVIOR OF DIMETHYL ETHER AND AMMONIA: A COMPARATIVE STUDY

The mixtures of ammonia/dimethyl ether (DME) are increasing in importance because DME can compensate for the limiting properties of ammonia (like autoignition temperature and flame speed). This work aims to develop a comprehensive kinetic mechanism describing the pyrolysis and oxidation of the mixtures of the two species. The critical aspects are the binary interactions, which are the focus of this investigation. Different experimental sets were used to validate the mechanism proposed. The model works reasonably well considering the uncertainty intervals. In addition, different models were used to make a comparison considering the same experimental data.
