Numerical Investigation on the Flame Characteristics of Lean Premixed Methane Flame Piloted with Rich Premixed Flame

Energies
The introduction of the pilot flame can stabilize the lean premixed flame and promote its industrial application. However, the interaction mechanism between the pilot and main flames is complicated.

Flame structure simulation in a methane/air coflow partially premixed burner

Revista Facultad de Ingeniería Universidad de Antioquia, 2014
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.
