Abstract: The transient development of the smoke layer due to a steady fire source in cubic atria was studied experimentally with a physical scale-down model. Scaling laws for scale modelling study were reviewed. Plume equation and correlation equation in literature for studying natural smoke filling with a steady fire were discussed. The clear height of the smoke layer was measured experimentally and correlated with the heat release rate of the fire and the time from the fire started in the atrium model base. The experimental results were compared with the measurements from a full-scale experiment through the preservation of the Froude number. The results were then applied to predict the time required to fill 80% of atrium height with smoke for cubic atria in the Hong Kong Special Administrative Region (HKSAR). Comparisons with those predicted by the plume equation and the correlation equation were made.
