Analysis of FDS Thermal Detector Response Prediction Capability

摘要

Predictions of fire plume and ceiling jet temperature and the response of thermal detectors from NIST's Fire Dynamics Simulator (FDS) were compared to data from a series of full-scale tests conducted by Underwriters Laboratory. The tests were conducted in a 36.6 m x 36.6 m compartment with ceiling heights ranging from 3.0 meters to 12.2 meters. Heat release rates followed a modified t2 growth profile. Thermocouples attached to brass disks were used to simulate thermal detectors. FDS simulations were conducted with a grid spacing of 100 mm.
