Modeling Train Fires in Fire Dynamic Simulator Melbourne, Australia

This project focuses on developing a passenger train car model using Fire Dynamic Simulator (FDS) to predict heat release rates (HRR) during fire incidents. It aims to create a modifiable model for future simulations while improving understanding of material properties and fire dynamics in train compartments. The approach includes analyzing full-scale experiments and running simulations to compare predicted outcomes with real-world data. This work supports ongoing improvements in fire modeling and provides invaluable insights for safety research, with personal growth from cultural experiences in Australia.
