DOI: 10.1016/j.combustflame.2017.10.014
Abstract: Abstract Here, we study real gas effects on high-pressure combustion by comparing simulated and experimentally-measured shock tube ignition delay measurements for n-dodecane/O2/N2 mixtures. Experiments and simulations occur at conditions relevant to diesel engines: 40–80 atm, 774–1163 K,… read more here.

DOI: 10.1016/j.combustflame.2018.05.022
Abstract: Abstract The high ignitability of diethyl ether (DEE) reflected by a high cetane number of ∼125 leads often to unintentional far-endwall ignitions in shock tubes. This is the main reason why exclusively diluted DEE experiments… read more here.
