Design Approaches: Performance: Fire Modelling

The most advanced and sophisticated fire modelling technique is the use of Computational Fluid Dynamics (CFD) models to predict fire growth and compartment temperatures. CFD models have been shown to be successful in the modelling of smoke movement and have recently been applied to the modelling of fires.
