The existence or non-existence of the negative temperature coefficient (NTC) region in cyclo-hexane (cyC6H12) oxidation is still an open question in the literature. This paper addresses this issue by presenting the rapid compression machine (RCM) and shock tube (ST) data and a consistent model to predict ignition delay times in agreement with experimental data. To this end. a semi-det... https://www.duospiritalis.com/
