介绍单层多房间建筑室内火灾数值模拟的验证研究。模型的计算值与 L uo和 Beck的实验结果进行了比较。为了考虑火灾的燃烧过程 ,采用 L aminar Flamelet方法。多房间建筑内热辐射的计算则使用 DOM(discret ordinates method)方法。在验证工作中 ,最困难的工作是通风不良条件下火灾的模拟。由于在低含氧量的情况下 ,火焰的燃烧特性并没有得到很好的认识 ,因此对燃烧模型并没有引入任何的修改 ,以便保留处理燃烧过程方法的通用性以及便于检验 L aminar Flamelet燃烧模型的能力。模拟结果与 L uo和 Beck的实验值能很好吻合。
Study on the Numerical Simulation of Indoor Fire in Single - storey Multi - room Building. The calculated values of the model are compared with those of L uo and Beck. In order to consider the combustion process of the fire, the L aminar Flamelet method was used. The calculation of thermal radiation in multi-room buildings uses the DOM (discreet ordinates method) method. The most difficult part of the verification work is the simulation of fires in poorly ventilated conditions. Since the combustion characteristics of the flame are not well understood at low oxygen levels, no changes have been made to the combustion model in order to preserve the versatility of the process for handling the combustion process and to facilitate the testing of the Laminar Flamelet combustion model Ability. The simulation results agree well with the experimental values of Lu and Beck.
