Abstract

Stable species concentration profiles were measured in a variable pressure flow reactor for dilute, near-stoichiometric ethanol oxidation at 12.5 atm and at temperatures ranging from approximately 525-905K, covering a range of temperatures for which few data on ethanol oxidation exist. Predictions based upon a previously developed high and intermediate temperature ethanol oxidation model are compared with the new experimental data. Based upon the above work, a hybrid n-heptane/iso-octane primary reference fuel (PRF) + ethanol oxidation model is developed, Predictions of the hybrid model are compared with the recently published ignition delay data for a 44.65/14.6/40.75 mole% mixture of isooctane/n-heptane/ethanol. Predicted ignition delay times are generally better than within a factor of two of experimental measurements.
