- Abstract
- Prediction of the spread of combustion gases from a fire is a major area of interest when analyzing
buildings from a safety point of view. Hence programs with this aim are continuously being
evaluated for the estimation of their validity. The purpose of this report was to produce and
compare complementary results for an up to date version of the program Fire Dynamics Simulator
(FDS) to what was previously done on the spread of combustion gases in a retail store according to
the report Holmstedt, 2008. A thorough sensitivity analysis was done on three different areas to
assure the validity of the new simulations made. Analysis showed that grid independent simulations
were conducted and that simulation data could be viewed as valid.... (More) - Prediction of the spread of combustion gases from a fire is a major area of interest when analyzing

were conducted and that simulation data could be viewed as valid. Results show no distinct
indications for the fire of the scenario to be under ventilated as predicted due to the limited
ventilation of the compartment. Comparison of the results from the simulations with experimental
results showed that the program has a good ability to predict the spread of combustion gases and
their temperatures in the upper layers for the type of compartment examined. An overestimations of
temperatures could be identified for the lower parts of the room compared to the experimental data,
with possible causes discussed in the report. Insecurity factors could be identified for this study that
also are further discussed in the report. (Less)
