air curtains flow fields f low lines potent ial f low prevent ing-smoke
The purpose of smokeproof design for high-rise building is to prevent harm f rom smoke and to cont rol smoke-dif fusing. The effect ive smoke-prevent ing installat ion should have the funct ions such as absolute smoke insulat ion, going into and coming off the smoke-prevent ing place f reely, no conf inement of sight. T hrough analyzing smoke-flow f ield theoret ically, it is discussed that the effect of air flow on a hig h-rise building is a result of gas ex pansion by the temperature, the chimney effect , the outdoor w ind pow er and the vent ilation and air-conditioning system when firing. The f low field at the staircase door is theoret ically found. The w ay in w hich the diffusion of smoke is cont rolled is adv anced according to the principle of f low line-flow rate and based on the previous experimental researches by others, the calculat ion method for the smoke-prevent ing air curtain is infered in this paper.
