Abstract
Full-scale experiments are carried out to investigate the influence of the vent surface on the temperature and the depth of the smoke layer in the steady state regime, in a largely used geometry. A series of experiments is conducted with a real scale room with hexane gas burner as heat source. Under various conditions of heat release rate (330 kW, 440 kW, and 550 kW) and ceiling vent area, the steady state local temperatures in the room volume are measured. It is shown that the opened surface of the ceiling vent contributes to a lower temperature of the smoke layer and to a higher position of its interface. It is confirmed also that the heat release rate of the fire plays a primordial role in the elevation of the depth and the temperature of the smoke layer.
