The structure and the mechanism of extinction of partially premixed diffusion flames is analyzed on the basis of a model that uses a one-step irreversible reaction with a large activation energy. Close to extinction the inner flame structure is essentially that of the Lifiin diffusion flame regime w
A theory is developed to explain the experimentally observed extinction of premixed flames by steep pressure drops. The full nonlinear equations are solved numerically and it is found that for large, rapid pressure drops the flame does not recover. This is taken to be clear evidence of extinction. M
The extinction of laminar premixed flames under the influence of stretch is studied experimentally and numerically. Experiment involves measuring the velocity field of methane/air and propane/air flames in an opposed jet with a laser Doppler velocimeter and computations are made using several chemic
Based on literature analytical and computational results that Le ΟΎ 1 premixed flames are susceptible to exhibit pulsating instability, and that such propensity is promoted with increasing positive stretch, experiments were conducted on counterflow twin flames of lean and rich mixtures of methane in
An axially stretched, cylindrical premixed flame was formed by using a radial-flow nozzle burner, which made it possible to produce a highly stretched flow field in laminar conditions and to investigate the extinction characteristics of the flame over a wide range of equivalence ratios. Using this b
