Experimental and theoretical investigation of partially premixed diffusion flames at extinction

· Combust. Flame; (United States)
The structure and the mechanism of extinction of partially premixed diffusion flames is investigated theoretically and experimentally for the practically important case of small values of the stoichiometric fuel-to-mass ratio. The theory predicts two nonequilibrium flame structures that are also observed experimentally. The predicted ratio of extinction Damkoehler numbers is compared with measurements of the ratio of velocity gradients at extinction. Although the comparison shows systematic differences, the prediction of a decrease of this ratio with increased premixing is confirmed. 13 references.
