This simple 3D Cartesian model demonstrates the fire modeling capability of CFD2000.  The source for the fire is located in the kitchen area.  The heat from the fire quickly spreads throughout the small apartment.  The model specifies fire time duration, pre-combustion temperature, heat of combustion, efficiency, and other parameters to define the fire simulation model. 

The fire modeling capability allows for the specification of heat and mass sources.  Fire time duration, pre-combustion temperature, heat of combustion, efficiency, and other parameters are used to define the fire simulation model.

Tunnel fire and smoke back-layering phenomena can be easily modeled using CFD.

A classical example of a laminar diffusion flame, first described quantitatively by Burke and Schumann, is shown here.  This CFD model uses a 2-step [H2+O2] reaction equation.

Transient CFD calculation of how long it takes smoke to reach a detector, and the concentration of smoke over time.  CFD results used to optimized internal sensors within the smoke detector housing.

CFD calculation of smoke dispersion from an electric arc furnace within a steel mill.  Color coding indicates temperature of ambient air in a vertical cross section within the building; orange shading shows location of smoke plume.  Environmental engineers are use CFD to help design and optimize ventilation systems critical to protecting worker’s health.
