abstract = {<p style="text-align: justify;">Modelling based on Computational Fluid Dynamics (CFD) is by now
effectively used in fire research and hazard analysis. Depending
on the scenario, radiative heat transfer can play a very important
role in enclosure combustion events such as tunnel fires. In this work,
the importance of radiation and the effect of the use of different approaches
to account for it were assessed. Firstly, small-scale tunnel fire simulations
were performed and the results compared with experimental data, then realistic
full-scale scenarios were simulated. The results show up the capability of CFD
modelling to reproduce with good approximation tunnel fires. Radiation proved to
be noteworthy mainly when the scale of the fire is relatively large. Among the
various approaches employed to simulate radiation, the use of the Discrete Transfer
model gave the most accurate results, mainly when the absorption-emission characteristics
of the combustion products were taken into account. Finally, the suitability of the
use of CFD in quantitative Fire Hazard Analysis is discussed.</p>},
