摘　　要：采用NFPA92B所提供的烟气控制计算公式对某奥运体育场馆的排烟量进行计算,并利用CFD数值模拟软件对排烟系统及补风系统进行优化设计,研究在该体育场馆内机械排烟,机械补风,自然补风三者之间的内在联系以及机械补风量对某馆排烟系统的影响。对该奥运体育场馆排烟系统以及补风系统的优化设计提供了理论依据。This paper makes a calculation of the smoke evacuation volume in a certain Olympic gymnasium by using the smoke control formula from NFPA92B, and makes an optimization design of the smoke evacuation and ventilation system by using the Computational Fluid Dynamics （CFD） stimulation software. It also discusses the inner relationship among the mechanical smoke evacuation, the mechanical ventilation and natural ventilation as well as the influence of the mechanical ventilation volume on the smoke evacuation system in the Olympic gymnasium, which provides the theoretical basis for the optimization design of the smoke evacuation and ventilation system in the Olympic gymnasium.

关 键 词：体育馆 排烟系统 补风系统 性能化
