Ignition delay times of NH3/DME blends at high pressure and low DME fraction: RCM experiments and simulations (open access)

Ignition delay times of NH3/DME blends at high pressure and low DME fraction: RCM experiments and simulations

Authors of the article describe how autoignition delay times of ammonia/dimethyl ether (NH3/DME) mixtures were measured in a rapid compression machine with DME fractions of 0, 2 and 5 and 100% in the fuel. Analysis of the mechanism indicates that this 'early DME oxidation' generates reactive species that initiate the oxidation of ammonia, which in turn begins heat release that raises the temperature and accelerates the oxidation process towards ignition. This is the accepted manuscript version of the published article.
