| Abstract |
In order to improve safety of the road and rail networks, this project proposes the development of an informatic tool for the numerical simulation of fires in tunnels. The tool to be developed will be able to take into account the air flow, the heat exchange and the possible structural damage of the tunnel facility. The effect of fire extinction mechanisms such as forced ventilation and sprinkler's action will be also taken into account
The physical models proposed for the simulation of such phenomena are relatively advanced. The simulation of the air flow will be performed using low Mach number models; the heat exchange model will take thermal radiation into account including the effect of smoke and soot and the structural model for the concrete will take damage into account including hydration and dehydration processes.
The numerical formulation of such models is considered as pioneering in the literature of numerical methods for fluid and solid mechanics. We propose the approximation of physical models using a stabilized finite element formulation for the spatial discretization including error estimation and automatic mesh adaptation techniques. It is to be noted that the two subprojects this coordinated project is composed are being presented by groups whose main research field is numerical simulation of physical processes. |
