The Effect of Air Velocity on Heat Release Rate and Fire Development during Fires in Tunnels
نویسنده
چکیده
Model scale fire tests using wood cribs of different porosity in a ventilated tunnel are presented. The study focuses on the effect of air velocity on maximum Heat Release Rate (HRR) and fire growth rate. To study the influence of different parameters, free burn tests and fire tests inside a model-scale tunnel were performed. The tunnel was 10 m long, the widths used were 0.3 m, 0.45 m, and 0.6 m and the heights used were 0.25 m and 0.4 m. If compared to a normal traffic tunnel, these measures can correspond to a tunnel with a scale of 1:20.

The critical ventilation velocity in tunnel fires—a computer simulation
In ventilated tunnel fires, smoke and hot combustion products may form a layer near the ceiling and flow in the direction opposite to the ventilation stream. The existence of this reverse stratified flow has an important bearing on fire fighting and evacuation of underground mine roadways, tunnels and building corridors. In the present study, conducted by the National Institute for Occupational...

Fire safety is considered as one of the major objectives in design, construction and specially tunnel operation. The hot and toxic smoke propagation is a fundamental reason of human losses during a fire inside the tunnels. Therefore, an exact analytical investigation on the probable fire scenarios and its destructive effects for passengers, vehicles and structure are the main part of the tunnel...

In this study, the amount of generated pool fire, as a result of the release of chemicals in the case of an accident in tunnels, was simulated and the results were compared to the experimental data. At first, various amounts of spatial resolution (R*) were considered to compare the existing experimental data at different heights at the upstream, downstream and above the pool fire...
متن کاملEstimation of Rate of Heat Release by Means of Oxygen Consumption Measurements
Intuitively, the rate of heat release from an unwanted fire is a major indication of the threat of the fire to life and property. This is indeed true, and a reliable measurement of a fire’s heat release rate was a goal of fire researchers at NBS and other fire laboratories at least as early as the 1960s. Historically, heat release measurements of burning materials were based on the temperature ...
