Abstract [en]

To investigate how different configurations in a large room affect the smoke spread and

temperature during a fire, eleven tests were performed. The tests scenario was built in scale

1:2 and can be described as a large room with small ventilation openings near the floor. The

fire tests were simulated using the CFD (

computational fluid dynamics) code FDS (Fire

D

ynamics Simulator). To see how well FDS simulates under-ventilated fires, both well

ventilated and under-ventilated cases were selected for the validation. Gas temperatures

and oxygen concentrations for the experiments and the simulations, respectively, are

compared. The results of the validation show that the combustion model (mixture fraction

combustion model), with empirical amendments for when the fire is allowed to burn, is very

sensitive to changes in the oxygen level.
