Abstract

The basic concepts of fire suppression systems are depicted. There are mainly two water-based fire suppression systems used in tunnels, that is, water spray systems and water mist systems. The main differences are the water density, pressure, and droplet size. The extinguishment mechanisms are explored and the critical conditions at extinction are discussed. Further, suppression of realistic fires is discussed considering both the water flow rate and the total water flow rate used for fire suppression. A summary of fire suppression tests carried out in tunnels is presented followed by a short discussion of tunnel fire detection.
