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 ...
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 ...
