The unexpected finding of the quasi-steady state cool flame onboard the International Space Station motivated increasing interests to study the dynamic behaviors of cool flames. One key scientific question is how to form and stabilize a self-sustaining steady-state cool flame in a burner with well-defined boundary conditions. This paper numerically studied the stabilization of a self-sustaining steady-state premixed dimethyl ether/O2/N2 cool flame. The dual S-curve response in the perfectly-stir...

ABSTRACTExperimental 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 branching/propagation reactions, CO/HCO reactions ...
