Abstract
This report investigates the potential of applying salt water modelling using the Laser Induced Fluorescence (LIF) flow visualisation technique to study balcony spill plume phenomena. A 1/20 scale perspex model was used to conduct a series of salt water experiments. The testing parameters include two balcony settings (125mm and 250mm in model scale) and two spilling densities (0.5% and 1.0% of salt by weight). Through the study, results showed that good flow visualisation could be achieved using the LIF technique. the main advantage of using the salt water modelling technique was the ease in modifying the model's geometry or testing conditions. These modifications would not result in huge changes in the data acquisition systems as in either the full or small scale fire tests.
