A Study of Fire Durability for a Road Tunnel: Comparing CFD and Simple Analytical Models
(ECCOMAS, J. Eberhardsteiner et.al. (eds.), 2008-08)
The durability of various typical tunnel sections in the event of a prescribed 100 MW fire has been assessed. Cast-iron sections, pre-cast concrete sections and in-situ concrete cut and cover sections are all considered ...
Calculation and design of tunnel ventilation systems using a two-scale modelling approach
(Building and Environment journal - Elservier, 2009-06)
This paper develops a novel modelling approach for ventilation flow in tunnels at ambient conditions (i.e. cold flow). The complexity of full CFD models of low in tunnels or the inaccuracies of simplistic assumptions are ...
Ventilation and Suppression Systems in Road Tunnels: Some Issues regarding their Appropriate Use in a Fire Emergency
(Tunnel Management International, 2009-03)
Two important tunnel safety technologies are addressed. The majority of long road tunnels have ventilation systems. In the event of a fire in a tunnel, such systems will influence fire development in a number of different ...
Tunnel ventilation effectiveness in fire scenarios
(FS-World Magazine, 2010)
Throughout most of a tunnel network the ventilation behaviour may be approximated with a simple 1D flow model. However, there are some important - but relatively small - regions of the tunnel that require CFD analysis. The ...
Analysis of the ventilation systems in the Dartford tunnels using a multiscale modelling approach
The capabilities of the ventilation systems in the two road tunnels at Dartford (London, UK) are analysed using a multi-scale modelling approach. Both tunnels have complex semi-transverse ventilation systems with jet fans ...
