Abstract
The study used for the elaboration of this article presents the influence of the heat release rate (HRR) on the hot gas layer and temperature development in a specified fire compartment with natural ventilation. The influence of the ventilation factor and the thermal properties of the internal linings (chipboard, gypsum board and expanded polystyrene) are considered as well. Two fire scenarios are taken into account, namely, the compartment has a door opening, respectively a window opening, the heat flow released by fire taking, on the row, the values of 250 kW, respectively 500 kW. Also, it uses the empirical method of McCaffrey, Quintiere and Harkleroad (MQH) to estimate the temperature of the hot gas layer inside the fire compartment.
