| Summary: | All tunnels require ventilation to maintain acceptable levels of contaminants produced by vehicle engines during normal traffic operation (normal ventilation), and to remove and control smoke and hot gases during a fire emergency (emergency ventilation) ref. (7). To protect passengers, personal and equipment in a tunnel fire, it is important to understand and predict the temperature distribution through the tunnel during the tunnel fire. In this paper, a computer program (Tunnel) has been built to investigate the temperature profile along the tunnel for passenger car and three passenger cars with and without ventilation by using (explicit F.D) method . In this paper, also we will study the effect of the system ventilation on the temperature profile and estimate the required time to return temperature to ambient value for passenger car and three passenger cars |
