Abstract

The smoke filling process for the three types of atrium spaces commonly built in Hong Kong are simulated using the two types of deterministic fire model: zone models and field models. The zone models used are the FIRST, CFAST, and CCFM.VENTS models developed at the Building and Fire Research Laboratories, NIST, USA and the NBTC one-room model of FIRECALC developed at CSIRO, Australia. The field model is a self-developed fire field model based on computational fluid dynamics theories. The results predicted by the two approaches are very similar. Simulation using a field model requires much more computing time compared with the use of a zone model, but it can give more detailed information on the fire-induced flow and temperature fields.
