The relation between the rate of entry of air into a fire cell and the so-called ventilation parameter was studied in a series of reduced-scale experiments. It was found that, during the period of full development, the fire plume plays a significant role in the movement of the air and the effluent fire gases. The fire plume acts as a primitive jet pump and may increase the throughput of gases, in relation to that attributable to the two-layer flow mechanism, by as much as a factor of 2. A tentative model of the plume- augmented ventilation mechanism is offered.
