Structure of partially premixed n-heptane–air counterflow flames
To avoid the complexities associated with the droplet/vapor transport and nonuniform evaporation processes, a fundamental investigation of liquid fuel combustion in idealized configurations is very useful. An experimental–computational investigation of prevaporized n-heptane nonpremixed and partially premixed flames established in a counterflow burner is described. There is a general agreement ...
متن کاملEffect of pressure on counterflow H2–air partially premixed flames
A computational investigation of high-pressure hydrogen–air partially premixed flames (PPFs) is reported to characterize the effect of pressure on the flame structure, and the relevance of reaction limits for these flames. The flames are computed using the Mueller mechanism consisting of 19 elementary reactions and 9 species. Although the mechanism has been validated during previous investigati...
متن کاملStructure and Extinction of Heptane/Air Partially Premixed Flames
A numerical investigation of the structure and extinction of n-heptane/air partially premixed ames in a counter ow con guration is reported. The ame is computed using a detailed reaction mechanism consisting of 275 elementary reactions and 41 species. The mechanism is validated by comparing its predictions with measurements for both the premixed and nonpremixed ames. The partially premi...

متن کاملInvestigation of the transition from lightly sooting towards heavily sooting co-flow ethylene diffusion flames
Laminar, sooting, ethylene-fuelled, co-flow diffusion flames at atmospheric pressure have been studied experimentally and theoretically as a function of fuel dilution by inert nitrogen. The flames have been investigated experimentally using a combination of laser diagnostics and thermocouple-gas sampling probe measurements. Numerical simulations have been based on a fully coupled solution of th...
