项目摘要

The proposed research program deals with fire safety in tunnels and large spaces such as subway stations and atria. The research, which aims at improving the effectiveness of active fire protection systems in these areas, combines both experiments and computer modelling. The experimental work will be performed in the newly constructed full-scale fire research facilities of Carleton University. These facilities, which are adjacent to NRC's full-scale Fire Laboratory, include a tunnel, and a 10-storey atrium both of which are served by a high capacity ventilation system. The proposed work is divided into four distinct areas: in the first area the research is focused on developing procedures for measuring experimentally the heat release rate of large fires occurring in both the tunnel and the atrium; the second area deals with atrium smoke management systems and the impact of make-up air velocity on their effectiveness; the third area will investigate fire detection systems in tunnels; and the fourth area will study the interaction between tunnel ventilation and suppression systems. In all proposed research areas both computer modelling using computational fluid dynamics models and experiments will be used. Comparisons between experimental data and model predictions will be made for model validation. In addition the models will be used to develop correlations and guidelines for the design of these systems.

拟议的研究计划涉及隧道和大型空间，如地铁站和中庭的消防安全。该研究旨在提高这些地区主动消防系统的有效性，结合了实验和计算机建模。实验工作将在卡尔顿大学新建的全尺寸火灾研究设施中进行。这些设施毗邻核管理委员会的全尺寸消防实验室，包括一个隧道和一个10层高的中庭，两者都有高容量的通风系统。拟议的工作分为四个不同的领域：在第一个领域，研究的重点是开发程序，实验测量发生在隧道和中庭的大火灾的热释放率;第二个领域涉及中庭烟雾管理系统和补充空气速度对其有效性的影响;第三个领域将调查隧道火灾探测系统;而第四个范畴则会研究隧道通风系统与灭火系统之间的相互作用。在所有拟议的研究领域都将使用计算机建模使用计算流体动力学模型和实验。实验数据和模型预测之间的比较将用于模型验证。此外，这些模型将被用来开发这些系统的设计的相关性和指导方针。
