Brief description: Several tunnel projects have recently proposed a ventilation principle with zero ventilation, i.e. that the ventilation speed is regulated down to 0 m/s in the tunnel to limit smoke dispersion in the t…
unnel. The principle is simulated and assessed in several studies, but the conclusions from the articles are sprawling. No physical tests have been seen on the principle on a large scale. The Norwegian Public Roads Administration c/o the Authority and Regulations would therefore like more knowledge
about the principle and the consequences this management can have. The assignment comprises a preliminary project as a basis for assessing the ventilation principle in road tunnels, as well as an option for testing the ventilation principle
