Abstract
The backdraft development process in a reduced-scale compartment of 1.2 m × 0.6 m × 0.6 m was visualized computationally. A three-dimensional (3-D) model-free simulation was performed using the fire dynamics simulator (FDS) developed by the National Institute of Standards and Technology (NIST) along with a global finite chemistry combustion model. Backdraft development, involving the gravity current of inflowing air, flame ignition, and flame propagation, was reasonably visualized with FDS. Additionally, the explosive fireball behavior passing through an opened window was well-simulated with the finite chemistry combustion model. The model-free simulation created using the FDS program and global finite chemistry combustion model can be used as an effective tool for visualization of backdraft phenomena.
