Public release of the NIST Fire Dynamics Simulator 2.0. (News Briefs).Official release versions of NISTs computer programs for modeling and visualizing fire and smoke flow, Fire Dynamics Simulator 2.0 and Smokeview 2.0, are now available for download at http://fire.nist.gov/fds/. The NIST Fire Dynamics Simulator predicts smoke and/or air flow movement caused by fire, wind, ventilation systems ventilation system Public health An air system designed to maintain negative pressure and exhaust air properly, to minimize the spread of TB and other respiratory pathogens in a health care facility , etc. Smokeview visualizes the predictions generated by the Fire Dyanamics Simulator. The Fire Dynamics Simulator is a computational fluid dynamics Computational fluid dynamics The numerical approximation to the solution of mathematical models of fluid flow and heat transfer. Computational fluid dynamics is one of the tools (in addition to experimental and theoretical methods) available to solve model which solves a form of the Navier-Stokes equations The Navier-Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, describe the motion of fluid substances such as liquids and gases. These equations establish that changes in momentum in infinitesimal volumes of fluid are simply the sum of dissipative viscous appropriate for low-speed, thermally-driven flows of smoke and hot gases generated in a fire. Version 2.0 of the Fire Dynamics Simulator includes improved combustion and radiation algorithms. Details of the numerical methods may be found in the Fire Dynamics Simulator Technical Reference Guide (NISTIR NISTIR National Institute of Standards and Technology Interagency Report NISTIR National Institute of Standards and Technology Internal Report 6783).
