Study of Influence of Smoke-Proof Pendant Wall on Fire Smoke Flow in a Building Corridor

Building corridor is the only way to pass in fire evacuation, at the same time, it is the main way for smoke to spread. A numerical simulation of the fire smoke flow in the typical room-corridor model is presented. The influence of smoke-proof pendant wall on fire smoke flow is obtained. The results shown that smoke-proof pendant wall can effectively prevent the spread of the smoke, and improve the efficiency of the smoke ejection of the fire area; the higher drooping height of the smoke-proof pendant is, the better smoke ejection effect you will get, on the premise of the safe evacuation, it should try to increase the drooping height of the smoke-proof pendant. When using the smoke-proof pendant to divide smoke zone, we should set smoke exhaust outlets in the central of the smoke zone.
