An experimental and analytical study of the ignition of methanol-oxygen-argon mixtures behind reflected shock waves was carried out over the temperature range 1300-1700K at pressures of 2.5 and 4.5 atm and equivalence ratios of 0.5, 1.0, and 1.5. 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 combustion indicated by the first visible light emission was reckoned as the ignition delay. The experimental ignition delay data were found to correlate with initial methanol and oxygen concentrations (mole/cc) and with initial temperature (K) by the relation that is presented. 35 refs.
