Abstract

Two series of full scale fire tests have been carried out with an objective to produce well-documented data for the zone model and CFD code verification. The first test series consisted of 21 tests in 10 x 7 x 5 m3 test enclosure with 2.4 x 3.0 m2 to ambient. The walls and ceiling were made of light weight concrete. Systematic variations of the fire size and locations were made to determine their effect on the fire environment. Burning rates, gas temperatures, wall temperatures, heat fluxes, flow velocities and species concentrations were measured during the tests. The second series consisted of eight tests in a 27 x 13 x 19 m3 test hall. Burning rates, gas temperatures and steel tube temperatures were measured to provide information about the smoke filling rate and heating of the steel structures. The boundary conditions were varied by changing the fire size and using mechanical exhaust of the smoke gas and open doors to ambient.
