In this presentation, Dr Liu will discuss some work done by himself and his research  group for real-world applications using CFD in fire safety engineering, including the  optimisation of fire suppression systems, the prediction of smoke movement in  buildings, and the role of CFD in arson fire scene investigation. In collaboration with  the FRNSW, a fire field model was developed within the research group to aid the  fire investigation of a tragic fire incident in an aged-care facility that caused 14  fatalities in Quakers Hill, Sydney, in Nov 2011. For the first time in Australia, the  numerical results were presented as evidence in court to convict the suspect for the  arson fire.
