Description

Fire Dynamics Simulator (FDS) serves as a free and open-source platform for the modeling and visualization of flows influenced by fire. This computational fluid dynamics code effectively solves a variant of the Navier–Stokes equations tailored for low-speed, thermally-driven airflow, focusing particularly on the transport of smoke and heat resulting from fires. Employing large-eddy simulation, it captures the intricacies of fire-plume dynamics and can be utilized in diverse scenarios, such as those involving wind, sprinklers, ventilation systems, and various materials that affect fire behavior. Users create scenarios by utilizing text-based input files, execute the calculations within FDS, and subsequently evaluate the output data. The simulator presents results from both FDS and CFAST simulations through advanced OpenGL-based 3D graphics, incorporating scientific visualization techniques that include animated representations of smoke and tracer particles, two- and three-dimensional shaded contours, iso-surfaces, temperature distributions, and flow vectors that display both direction and intensity. In addition to these features, FDS is continually updated to enhance user experience and functionality, making it a vital tool for researchers and safety professionals alike.

Description

The dispersion of plumes, puffs, and spills is modeled using Gaussian calculations and is presented through both tables and graphics, featuring six user-defined isopleths in an XY-slice at a crosswind distance. A comprehensive 3D "CAT-Scan" output is achievable, allowing for detailed dispersion analysis through "cake slicing" in XY (isopleth) graphs, with options for color graphics including custom, default, or black and white. This sophisticated dispersion model calculates mass and volume across various concentration zones and shells related to plumes, puffs, and evaporating spill pools, while also accounting for scenarios such as underground explosions, mechanical explosions in cylindrical or spherical vessels, and dust explosions, all linked to corresponding PROBIT values. Furthermore, the graphics produced are vibrantly colored, enhancing the visual representation of the data. Lastly, the fire load of any facility or industrial setup is quantified as the potential heat energy release per square meter of floor area within its compartments, emphasizing the importance of understanding fire dynamics in safety assessments.
