Abstract
Different models and solvers are used to calculate the spread of fire and smoke in a tunnel. The methodology for obtaining the numerical solution of this fire dynamics problem involves commercial software and a research program. Both can handle geometries described in three dimensions. Particular emphasis was placed on road tunnels in which vehicles are present. The specific application of this work is a study of a fire scenario in the Louis-Hippolyte-Lafontaine Tunnel which runs under a river in the Montreal area. Besides standard representation, visualization is also used, with elements which consider the optical properties of the phenomenon for a realistic rendering of smoke and fire.
