Recent areas of research

Computer modelling

Fire Dynamics Simulator (FDS)

FDS is available from the National Institute of Standards and Technology (NIST). The model has been extensively used for our research work. Recent projects have looked using FDS to model road tunnel fires and comparison with balcony spill plume measurements. Work is also ongoing to transfer CAD files into FDS.

BRANZFIRE screen shotBRANZFIRE

The BRANZFIRE zone model is developed by Colleen Wade at BRANZ Ltd. Research at the University helps Colleen add new modules to the software and provide verification of its capabilities. Work has added a glass fracture module to the software, examined the model's ability to predict sprinkler activation provided a method to automatically show building geometry by electronic data transfer.

Research is ongoing to develop a Monte Carlo risk-based version of the Model called B-RISK.
