Detailed and Reduced-Chemistry Descriptions for Ignition and Detonation of Propane

摘要

The chemistry of autoignition of propane is studied with the objective of developing reduced chemistry descriptions. A detailed mechanism of 165 reaction steps among 38 chemical species is identified. This mechanism is reduced to a short mechanism of 34 steps, by deleting steps that are unnecessary. In the short mechanism, steady-state species are identified for deriving a systematically reduced mechanism. Good agreement with measured shock-tube ignition times is found.
