Abstract
In a fire situation, two main aspects are determining causes of human death: the high temperature and the intoxication by smoke. In present work, it is analyzed the transient evolution of smoke layer thickness in different fire situations. It was performed comparisons between different experimental fire data such as: a large hall with only one opening of 0.2 m obtained by Li et al. (1999); a tunnel with two distinct Heat Release Rates (HRR) performed by Gao et al. (2016); a hall through the experiment performed by Lai et al. (2013) that have a vertical opening (door) of 2 m × 0.8 m, and a laboratory through the experiment performed by Yi et al. (2005). In all cases the results are obtained using the fundamental solution of the smoke equation and its analytical solution proposed by Novozhilov (2012), both applied to the same fire scenario. The results of the fundamental smoke equation presented good agreement with the experimental data for most of the fire scenarios tested.
