Flame Propagation in a Nonuniform Mixture: Analysis of a Propagating Triple-Flame [PDF]
Combustion Science and Technology, 1991 Abstract A situation in which a dilffusion flame reaches an end at some position in a medium of non-premixed reactants is studied. The mixing of reactants that takes place ahead of the diffusion flame leads to the formation of a “triple-flame”, a structure which consists of a fuel-rich premixed flame, a fuel-lean premixed flame, and a diffusion flame ...
