公路隧道CFD建模火灾研究与实验验证

以一段实体隧道为背景，建立计算流体动力学模型，模拟了60 L汽油火灾产生的温度场及其变化，并通过实验进行了比较。温度的模拟值和试验值无论是同一高度不同地点，还是同一高度不同时刻，在总体变化趋势上基本是一致的，而且模拟值相对试验值而言，对工程实际是偏于安全的。实验证明所建立的CFD模型是可靠的，可用于下一步大规模火灾的研究。

CFD Modulation and Experimental Verification of Fire Hazard in Highway Tunnel

This paper establishes computational fluid dynamics model for a real high-way tunnel to simulate temperature field and its changes generated by a 60L gasoline fire and compares the numerical result with the experimental result. The overall trend of simulation and experiment is substantially same either at different locations of the same height, or the same height or at different times and the simulation values are higher than the experiment values. Experiments prove that the established CFD model is reliable and can be used for large-scale fire research next.
