摘要: The current paper describes the investigation of parameters related to accidents in tunnels framework "Advanced Training System for Emergency Management" project, A-TEAM. On this basis, flow field is investigated within tunnels, and its effects on fire development smoke concentration fields these emergency cases are reconstructed. This achieved with use Computational Fluids Dynamics (CFD) model CFX-5. has been applied two Switzerland: Belchen, a one-directional road tunnel, Grauhotz, bi-directional railway tunnel. simulations identify direction trains/traffic resulting fields, show that at low ventilation areas, accident releases lead increased levels.
