Abstract

During a fire accident, smoke has been reported to be the main cause of heavy casualties. Hence, smoke management play an important role on escape. Fire Dynamics Simulator software (FDS) was utilized to carry out full scale numerical simulations of fire accident in a flat large space building. According to the simulation result, with the increase of area of natural ventilation vents, the efficacy of smoke confinement didn’t change appreciably when only thermal pressure acted on the windows. However, the efficacy became obviously better when both wind pressure and thermal pressure acted on the windows. When the wind pressure played a role on the east external windows and the smoke emission rate remained constant, the efficacy of smoke management was better. The velocity of the exhaust smoke from east external windows had pronounced change of the smoke management. When the velocity increased to 2m/s, the efficacy was the best. In addition, when the height of the windows increased in 2m, the efficacy of smoke management became better.
