Numerical Simulation of Smoke Exhausts Function of Roof Vent in Compartment Fires
The influence of roof vent area and fire source area on smoke exhaust function of roof vent is provided in this paper. Numerical simulation results show that the temperature of hot smoke layer increases with the increases of heat release rate and decreases as the roof vent area increases. For the evaluation criterion with temperature difference, with the increase in roof vent area and fire source area, the smoke exhausts function of roof vent was enhanced. But for the evaluation criterion with efficiency of smoke exhaust, the smoke exhaust efficiency increases as the roof vent area increase and decreases with the increases of fire source area.
