Model scale tunnel fire tests with water-based fire suppression systems

• A total of 18 tests were carried out in the 1:4 model scale tunnels with water-based fire suppression systems together with one free-burn test. The key parameters including fuel load covers, activation time, water flow rate, nozzle type, ventilation velocity, sprinkler section length and tunnel width were tested. Technical information and analyses of test data are presented in this report with a focus on the influence of these different parameters on the design fire in a tunnel with a water-based fire suppression system. Further, guidance for the design fires in tunnels with water-based fire suppression systems is proposed.
