Abstract
A 0.76 by 0.76 m (30 bY 30 inch) enclosure with a 0.61 m (24 inch) high ceiling was used to model some fires in a 3 x 3 x 2.4 meter (10 x 10 x 8 foot) burnout room. Temperatures, oxygen concentrations, air velocity, and conductive and radiant heat fluxes were measured. The highest average air temperature in the upper part of the room was taken as a measure of the fire buildup potential of the room. Upper air temperatures attained in the model were similar in most cases to those in the full-scale compartment. From energy balance considerations this air temperature was related to the oxygen depletion in the room and was shown to correlate will with the oxygen content of the combustion gas and air exhausting from the modela nd full-scale room fires.
