Improving the Prediction Accuracy of the Extinction of Stretched Methanol/Air Premixed Flames

Experimental measurements of the laminar flame speed and extinction strain rate of premixed methanol/air flames were conducted using the counterflow configuration. The validities of five methanol oxidation chemical kinetic models were verified. The results showed that a notable discrepancy was observed between the experimental and predicted extinction strain rate. Sensitivity analyses showed that the dominating reactions were H2/O2 chain...
