| An Experimental and Analytical Investigation of High Temperature Ignition of Ethanol, (9999) | |||||||||
Abstract | |||||||||
| An experimental and analytical investigation of the ignition of ethanol-oxygen-argon mixtures behind reflected shock waves was carried out over the temperature range 1300-1700K at pressures of 1.0 and 2.0 atm and equivalence ratios of 0.5, 1.0 and 2.0. In the experimental investigation, ignition was identified by the emission of visible light in a shock tube. The time interval between the arrival of the incident shock at the end flange and the subsequent ignition indicated by the first visible light emission was reckoned as the ignition delay. The experimental ignition delay (t) data were found to correlate with initial ethanol and oxygen concentrations (mole/cc) and with initial temperature (K). A 56 step kinetic model for ethanol oxidation in the above temperature range was assembled using published rate coefficient data wherever available and estimated data for the reactions which have not been studied. Theoretical ignition delays were evaluated from the concentration profiles..
