Preignition Oxidation Chemistry of the Major JP-8 Surrogate Component: n-Dodecane
01 Jan 2009
Abstract
Four experiments were conducted to study n-dodecane oxidation at 8 atm for equivalence ratios ranging from 0.23-0.88. The experiments were performed in a pressurized flow reactor under lean, dilute conditions, throughout the low and intermediate temperature regime (600-850 K) to investigate the preignition oxidation chemistry. Samples of intermediate species produced during the oxidation process were collected and analyzed utilizing gas chromatography with flame ionization detection, coupled with mass spectrometry. The identity and quantity of intermediate species produced were similar when comparing the Moderate to High equivalence ratio experiments. However, major differences were apparent when the Moderate and High Phi experiments were compared to the Low equivalence ratio experiment Experimental results were compared to a semi-detailed kinetic model representing a Moderate Phi n-dodecane experiment. The model predicted the general trends of CO and CO sub(2), and the consumption of n-dodecane and O sub(2), reasonably well. Quantitatively in terms of n-dodecane consumption and carbon oxides production, the model underpredicted fuel reactivity, particularly at temperatures above 700 K.
