【Abstract】 Studies the smoke filling in an airport terminal hall with field model and body fitted coordinate technology. The results show that it takes a relatively long time for smoke to reach the height which is necessary for evacuation, and with the increasing of the heat releasing rate of fire, the velocity of ceiling jet and smoke temperature increases and the height of smoke layer decreases.更多还原
