The smoke-filling process in atria of local shopping malls was studied. The scenario of smoke spreading from a shop located adjacent to an atrium was considered. A two-layer zone model, CL-Atrium, was developed with balcony spill plume. Three plume expressions due to Thomas et al., Poreh et al. and NFPA-92B were used and assessed. Comparison was made with simulations due to CFAST. It is found that a condition has to be satisfied for the plume expression due to Thomas et al. Further, the results on the smoke layer temperature and interface height in the atrium are similar while using the plume expressions by Poreh et al. and Thomas et al.
