Abstract :
Outbreak of fire in isolated places is always related to the emission of harmful substances, increasing the air temperature and decreasing the level of oxygen. These parameters of the environment are very dangerous to occupants. This current work is carried out using numerical solutions of the distribution of smoke and hazards in confined and large spaces with and without operation at ventilation systems. In the process of numerical solution different schemes of air suction and supply are modeled and studied. Different turbulent models are tested in order to achieve the sustainable solution.
