Abstract: | Computational tools such as one-dimensional models or Computational Fluid Dynamics (CFD) have been used for the fire safety
design of road tunnels. However, most of these analyses are performed using a specified fire source where the heat release
rate (HRR) in the tunnel is fixed by the user and the influences of ventilation conditions and tunnel geometry are not considered.
For a more realistic estimate, models need to incorporate these factors in their input. This paper discusses the use of a
statistical approach previously developed by other researchers (Carvel and Beard, The handbook of tunnel fire safety. Thomas
Telford Publishing, pp 184–197, 2005) and the use of a CFD approach to estimate the HRR in a road tunnel fire. As an application
example, fire scenarios in which a light goods vehicle carrying wooden pallets are used to compare the estimation of the HRR
using these two methods. |
