Abstract
The present study has been performed to evaluate the reliability of the fire field model (FDS version 5.2) with yield rate concept of combustion products. The CO and smoke density predicted by FDS model was directly compared with measurement in a reduced scale ISO-9705 room. The GER (global equivalence ratio) concept was used to characterize the CO and smoke density with ventilation condition in the fire compartment. The FDS model tends to under-predict CO concentration and smoke density than those of measurement for the under-ventilated conditions. Also, the discrepancy between predicted and measured result increases as GER increases. In order to improve the reliability of the fire model for performance evaluation of fire safety, the fire model is necessary to be validated in various fire cases as well as develop detailed physical model.
