| Abstract: | Smoke movement and the performance of static smoke extraction system in an atrium were investigated through a scale model of the cargo terminal. The objective is to study natural smoke exhaust for an atrium with a scale model. Both experimental and numerical studies were conducted to evaluate the performance of smoke exhaust systems. A small scale model was set up to study the smoke movement. Whether the system is effective in exhausting the smoke produced in a fire was tested through experiments. Smoke exhaust under a 13 MW test fire in the real scale model was studied. Numerical study using the Computational Fluid Dynamics Software Fire Dynamics Simulator to investigate fire and smoke behavior in the small-scale cargo model was conducted. Carrying out experiments with high heat release rate fire in the laboratory is restricted and of high risk. The small-scale conditions were set in the software with fire heat release rate and the simulation results were compared with small-scale experimental results. |
