Diesel oil pool fire characteristic under natural ventilation conditions in tunnels with roof openings

---

Abstract.
In order to research the fire characteristic under natural ventilation conditions in tunnels with roof openings, full-scale experiment of tunnel fire is designed and conducted. All the experimental data presented
in this paper can be further applied for validation of numerical simulation models and reduced-scale
experimental results. The physical model of tunnel with roof openings and the mathematical model of
tunnel fire are presented in this paper. The tunnel fire under the same conditions as experiment is simulated
using CFD software. From the results, it can be seen that most smoke is discharged directly off the
tunnel through roof openings, so roof openings are favorable for exhausting smoke. But along with the
decrease of smoke temperatures, some smoke may backflow and mix with the smoke-free layer below,
which leads to fall in visibility and is unfavorable for personnel evacuation. So it is necessary to research
more efficient ways for improving the smoke removal efficiency, such as early fire detection systems,
adequate warning signs and setting tunnel cap.
