    • A method and computer-readable medium for modeling smoke propagation in a structure are presented, along with applications of the method. A model is provided of a multiplicity of compartments within the structure, and the presence of a fire within a compartment is determined. The energy and smoke released by the fire is estimated, and smoke flows out of the compartment are determined. Each compartment having a smoke source is analyzed, individually, for the propagation of smoke. Each compartment is assumed to have a homogenous upper smoke layer and a lower cool air layer. The analysis includes a mass and energy balance to determine the change in characteristics of the upper smoke layer, where a known pressure for the lower cool air layer is used for the balance. For multiple smoke sources into a compartment, the contributions to the mass and energy balance of each smoke source are considered additive.
    • 提出了一种用于建模结构中烟雾传播的方法和计算机可读介质,以及该方法的应用。 在该结构内提供多个隔室的模型,并且确定隔室内的火焰的存在。 估计火灾释放的能量和烟雾,并确定烟雾流出隔室。 分别分析具有烟源的每个隔室用于烟的传播。 假设每个隔室具有均匀的上烟层和较低的冷空气层。 分析包括质量和能量平衡,以确定上层烟层的特性变化,其中下层冷空气层的已知压力用于天平。 对于隔室中的多个烟源,对每个烟源的质量和能量平衡的贡献被认为是添加剂。
