1. Modeling Train Fires in Fire Dynamic Simulator Melbourne, Australia Tara Barden Jason Brown Todd Hetrick

2. 2 Overview of Project

3. 3 Objectives Develop a passenger train car model to predict total HRR (heat release rate) Design a modifiable model for use in future simulations Gain an understanding of material properties and fire involvement

4. 4 The Approach Obtain an understanding of FDS software Knowledge of full scale experiment Make the FDS model of the train compartment –Ignition source –Fuel properties –Geometry –Instruments Run simulations to analyze model

5. 5 Model Assessment FDS versus full scale experiment results Analyze temperature, heat flux, and pressure predictions Visually compare smoke and fire plumes
