Title of Talk Large Eddy Simulations of Fire


Kevin McGrattan

National Institute of Standards and Technology


Abstract


The talk describes a methodology for simulating the transport of smoke and hot gases from fires inside and outside of enclosures. Efficient CFD techniques are used to solve the Navier-Stokes equations with a simple form of the large eddy simulation technique. The computations are three-dimensional and time-dependent. Due to the efficiency of the algorithm, calculations employing over a million computational cells are routinely performed on workstations and high-end PCs. A description of the underlying mathematical model and computational techniques will be presented, followed by examples ranging from small scale combustion experiments to full scale industrial fires to the dispersal of smoke plumes over complex terrain.
