Abstract
An experimental study on force-ventilated fires was made using 50 cm cubic model box with methanol as the fuel. From the experimental results, it was found that carbon monoxide generation becomes significant for stoichiometric fuel to air ratio greater than 1.0. The rate of fuel vaporization, the major factor governing the stoichiometric ratio, is found to be determined by heat flux to the fuel surface. Combustion characteristics within a force-ventilated enclosure are influenced by ventilation conditions. Inlet conditions are more influential than outlet conditions. For modeling the combustion characteristics and heat balance, the interdependency of these two factors must be taken into account.
