RENDON, Julio; CADAVID, Francisco  e  AMELL, Andrés. Flame structure simulation in a methane/air coflow partially premixed burner. Rev.fac.ing.univ. Antioquia [online]. 2008, n.44, pp.61-74. ISSN 0120-6230.

The effect of the equivalence ratio on the partially premixed methane / air laminar flame structure, in a coflow atmospheric burner was simulated. Three equivalence ratios were studied (Φ =1.6, Φ =2.0, Φ =3.5) keeping constant the released energy. The simulation was carried out using FLUENT V 6.2. The radial profiles of temperature and velocity were compared with the experimental data. The influence of the mesh structure in the solution was studied. A criterion to report the height of the flame from the OH profile was also defined. The effect of the equivalence ratio on the flame structure was analyzed from temperature and species contours. The typical structure of a partially premixed flame for the three equivalence ratios was obtained.

Palavras-chave : partially premixed flame; combustion simulation; methane/air laminar flames; coflow burner.
