- Abstract
- The combustion of methanol is examined under varying magnitudes of external heat flux and mass fraction of environmental oxygen. The flames have been observed to change from one-luminous to luminous for B(Rad)~3.2, where mass loss rate, and convective and radiative heat release rates show agreement with the values reported from combustion of large pools of methanol. For higher values of mass fraction of oxygen and external heat flux, the methanol flames become very luminous, unburnt soot is present in the products and the radiative fraction of the stoichiometric heat release rate reaches a value of about 0.30 to 0.40, which is also found for numerous polymeric materials and liquids, irrespective of their generic classes and of the amounts of unburnt soot. The maximum value of B(Rad) is 5.3. (Mass loss rate is equal to 25 g/m(2)s.) A change in the pyrolysis chemistry of methanol vapors apparently leads to flame luminosity (radiation) and soot formation.
