NUMERICAL MODELLING OF FIRE AND SMOKE DEVELOPMENT IN RAILWAY TUNNEL
Abstract eng: Simulation of fire spread and development of toxic gases during a fire accident in a rail tunnel allows prepare and validate models of safe evacuation of people. Highly complex problem of fire dynamics in a tunnel can be solved by the aid of CFD method. It can simulate the temperature resolution and toxic gases development in a tunnel, which can be together with visibility considered as the most important parameters affecting the safety of persons involved in tunnels accidents. In order to check the degree of qualitative agreement of model prediction, verification and validation process is applied. Prediction method of fire and smoke development by the aid of numerical model in FDS is applied to a real construction of tunnel Špičák.
