Three exergy zones are observed in this study by investigating the local percentages of kinetic exergy, chemical exergy, and thermal exergy of a typical non-premixed methane-air jet flame, the Sandia flame D. It is observed that the flame domain can be divided into three zones as (1) zone ÃÂ, the fuel zone where methane sprays and spreads, (2) zone ÃÂÃÂ, the air zone where air sprays and spreads, and (3) zone ÃÂÃÂÃÂ, the left area besides zone ÃÂ and zone ÃÂÃÂ in the flame domain, and this is the place where combustion occurs and flame spreads. Results show that zone ÃÂ and zone ÃÂÃÂ have higher local percentages of kinetic exergy and chemical exergy whereas zone ÃÂÃÂÃÂ has higher local percentages of thermal exergy.
