Ventilation system of road tunnel is one of the most important parts of the tunnel safety
equipment, especially in view of the emergency event in the tunnel with fire. Last year we …

The computer simulation of fire spread based on modelling of complex processes related to
fire by Computer Fluid Dynamics CFD theory should be a significant contribution to increase …

Fire safety of tunnels is an important issue which must be solved carefully during all phases
of preparation, building and operation of each road tunnel. In this paper some particular …

Adequate design methods and tools are vital to any construction project, especially when its
complexity and value are high. Tunnels, road or railway, are a good example of such …

The paper describes verification and validation of numerical model of fire and smoke
development in a railway tunnel carried out in numerical code Fire Dynamic Simulator. To …

Simulation of fire spread and development of toxic gases during a fire accident in a railway
tunnel allows prepare and validate models of safe evacuation of people. Highly complex …

In recent years, a number of fire accidents have occurred in several road tunnels over the
world. Many of these fires grew rapid to catastrophic size. Smoke as well as toxic gases from …

The work gives the study results for 1: 10 scale physical models of the road tunnels. The
tunnel slope changes from 0 to 10% with a 2% spacing. As the models show, the fire …

In recent years in Poland investment in more and more tunnel construction projects and has
taken place. Road tunnels are created both in complex urban and mountainous areas …

The definition of the deterministic approach in safety analyses arises from the need to
understand the conditions that emerge during a fire accident in a road tunnel. The key factor …
