射流风机在应急隧道通风中的应用，作为传统风机设备的一种具有经济吸引力的替代方案，在过去几年中在美国变得越来越流行。此外，最近的文献表明，交通隧道面临着越来越多的火灾荷载。例如，最新（2008）版的NFPA 502《公路隧道、桥梁和其他有限通道公路标准》指出，对于运输易燃和可燃液体的油轮，火灾热释放率峰值（FHRR）为200-300 MW（683–1025 MBtu/hr）。这是同一标准2004年版报告值的两到三倍。 更大的设计FHRR增加了对应急通风设备（如射流风机）热负荷计算准确性的需求，以避免这些设备的过度设计，并证明其可行性。幸运的是，随着计算能力成本的降低，这一趋势继续发展。因此，不可避免地需要使用更复杂的计算分析工具来分析设计火灾规模为100MW的大型火灾紧急情况下的射流风机性能。本文介绍了一个案例研究，其中三维CFD分析与一维SES分析结合使用，以确定射流风机配置，并证明射流风机的性能/符合公路隧道的紧急通风要求。 引文:内华达州拉斯维加斯ASHRAE会议论文

Application of jet fans in emergency tunnel ventilation, as an economically attractive alternative to traditional fan plants, has become more popular in the US over the past years. Also, recent literature indicates that transportation tunnels are facing increased fire loads. For example the latest (2008) Edition of the NFPA 502, Standard for Road Tunnels, Bridges, and Other Limited Access Highways, indicates peak Fire Heat-Release Rate (FHRR) of 200-300 MW (683 – 1025 MBtu/hr) for tankers carrying flammable and combustible liquids. This is two to three times the values reported in the 2004 Edition of the same standard. Larger design FHRR increases the need for accuracy in accounting for the heat loads on the emergency ventilation equipment such as jet fans in order to avoid significant over design of these equipment and demonstrate their feasibility. Fortunately, this trend continues to grow parallel to reduced cost of computational power. Therefore, it is inevitable that more sophisticated computational analysis tools are used in the analysis of jet fan performance under fire emergency conditions with large design fire sizes of order 100MW. This paper presents a case study, where the three dimensional CFD analysis is used in conjunction with one dimensional SES analysis in order to establish the jet fan configuration and demonstrate performance/compliance of jet fans for the emergency ventilation requirements of a road tunnel.
