Abstract: An investigation on the scenarios of the spill plume and its equation was presented,including two aspects,i.e.,the small-scale experiment and the numerical simulation. Two balcony spill plume models are assessed by comparing with the fire dynamic simulation (FDS) and small scale model experiment results. Besides validating the spill model by experiments,the effect of different fire locations on balcony plume is also discussed. The results show that the balcony equation in NFPA gives good predictions on the mass flow rate. And the balcony plume entrainment coefficient is independent of the fire location. This investigation is useful for the fire engineers in designing smoke control systems.
