Study on the Effect of Slope on Tunnel Fire Characteristics
Through the scale tunnel experiment, the effect of different gradients on the temperature distribution and longitudinal velocity of tunnel fire is studied. The experimental results show that the slope affects the temperature distribution of upstream and downstream, but there is a compensation effect. That is, the larger the downstream temperature rise caused by the slope effect, the smaller the upstream temperature rise correspondingly. At the same time, the heat release rate is also an important factor that affects the longitudinal velocity and temperature distribution under low slope situation and these characteristics are only related to the slope under high slope situation.
