CFD Modeling of Fire



Kevin B. McGrattan, Randall J. McDermott, Glenn P. Forney, Jason E. Floyd, Simo A. Hostikka, Howard R. Baum


An overview of a methodology for simulating fires and other thermally-driven, low-speed flows is presented. The model employs a number of simplifications of the governing equations that allow for relatively fast simulations of practical fire scenarios. The hydrodynamic model consists of the low Mach number large-eddy simulation subgrid closure with either a constant or dynamic coefficient eddy diffusivity. Combustion is typically treated as a mixing-controlled, single-step reaction of fuel and oxygen. The radiation transport equation is written in terms of a spectrally-averaged gray gas. Applications of the model include the design of fire protection systems in buildings and the reconstruction of actual fires.
