- Abstract
- Fire induced flows were measured in a 1/7th scale model room-corridor by measuring velocity and temperature profiles in the room and corridor exit doorways. The corridor exit door width was varied by a factor of 10 as an experimental parameter while the average fire room temperature was held constant. The applicability of an orifice flow model to predict the doorway flows was examined. The ratio of measured to theoretical mass flow rate, defined as the flow coefficient, was found to vary with door width and flow direction. The coefficient ranged from 0.4 to slightly greater than 1. No wxplanation has been developed to account for this variation.
