Data concerning smoke control from full-scale fire experiments conducted in the Runehamar Test Tunnel in Norway in 2021 are summarized and analyzed. The tests were carried out as a part of commercial testing program of high pressure water mist nozzles. These tests included two free- burn tests, and several tests with high pressure water mist based fire suppression systems but only the data prior to activation of the systems are of concern in this study. The data are compared with the established prediction model and demonstrate good consistency. Suggestion on future testing is also made.
The project is funded by the Tunnel and Underground Safety Center (TUSC), which is greatly acknowledged. TUSC is a research platform for fire safety in underground constructions. The partners are RISE, Swedish Transport Administration, Swedish Fortifications Agency, SKB - the Swedish Nuclear Fuel and Waste Management Company, and Swemin’s Health and Safety Committee (GRAMKO). The full-scale tests were a part of commercial testing of a high-pressure water mist system from Siemens A/S and carried out by RISE Fire Research AS in Norway. Thanks to Henrik Bygbjerg at Siemens for providing the research group with access to the smoke control data and the colleagues at RISE Fire Research in Norway who performed the tests.
