Abstract: Taking the Lijiao Metro Station in Line 3 of Guangzhou Metro as an example, the smoke control efficiency of the air curtain with different characteristic parameters (thickness, jet velocity and jet angle) is studied by FDS. The distinctions of smoke spread, temperature profile and visibility between different simulated scenarios are observed by comparing the numerical simulation results. The suitable range of parameters of the air curtain for the metro is determined.

Key words: FDS(fire dynamics simulator), subway fire, smoke spread, air curtain
