In this paper, the smoke filling process for the three types of atrium spaces are simulated u using the two types of deterministic fire model; zone models and field models. The zone models u used are the FffiST, CFAST, and CCFM.VENTS m떠els develo야퍼 at the Building and Fire R Research Laboratories, NIST, USA and the NBTC one-room model of FIR.ECAIι delveloped at C CSffiO, Austr;외ia. The field models used are the fire field model developed by W. K Chow and a a self-developed Sl1EP(Smoke Movement Estimating Program) based on computational fluid d dynamics the$alpha$1es. The results pn려icted by the two approaches are very similar. The field model u using SIl1PLE algorithm or SIl1PLER algorithm requires much more computing time compared w with the use of Sl1EP using PISO algorithm.
