A020 Scale smoke filling

Scale Modeling studies of smoke filling

Brief:

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 using scaling laws through the preservation of the Froude number. 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 and expressions from fire plume equations and correlation equations in literature for studying natural smoke filling with a steady fire. Applications of the time required to fill 80% of atrium height with smoke as a design parameter for cubic atria in the Hong Kong Special Administrative Region (HKSAR) were discussed.
