Numerical Investigations on Characteristics of Methane-Air Premixed Flame

Abstract:

The combustion reaction mechanism of methane plays an important role on combustion, environmental protection and propulsion areas. Numerical investigations on the characteristics of Methane-Air premixed flame were conducted in this paper. Results indicate that: intermediate products such as HCO, CO increase first and then decrease; CO distributes behind HCO and is converted from HCO; The distribution of OH radicals is one dimensional, and there are two high concentration regions, only the region at the exit of the premixed gas corresponds to the flame front; final products such as CO₂ and H₂O exist at the whole reaction area.
