Sammanfattning

Numerical experiments, constituting of 90 simulations in FDS, were used in this paper for two purposes. Firstly an evaluation of previously derived correlations for ceiling jet excess temperatures and velocities was performed. Secondly the numerical experiments were used to demonstrate how computer simulations could be used as a complement to actual fire experiments in fire science research.

The evaluation indicates that the existing correlations will give a good estimate of the average temperature in a ceiling jet. However, it seams like the correlations will not give a good estimate of the maximum excess temperature or velocity. Consequently, a new correlation to estimate the maximum temperature was developed. The novelty of this research is primarily the method that includes an outline of how numerical experiments can be used in fire science research.
