Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) model of fire-driven fluid flow. The computer program solves numerically a large eddy simulation form of the Navier–Stokes equations appropriate for low-speed, thermally-driven flow, with an emphasis on smoke and heat transport from fires, to describe the evolution of fire.
The NIST World Trade Center Disaster Investigation was a report that the National Institute of Standards and Technology (NIST) conducted to establish the likely technical causes of the three building failures that occurred at the World Trade Center following the September 11, 2001 terrorist attacks.

Exposures - stop fire spread Confine - contain the fire Extinguish Overhaul - check for hidden fire spread [1] - targets of opportunity: Salvage Vent Company Officer Checklist For Report On Conditions. SLICERS. Size up Locate seat of fire Identify flow path Cool from safe distance Extinguish fire Rescue Salvage
Here’s where the smoke from the Park Fire – the largest California fire of the year – is expected to go this weekend Interactive map shows forecasted path for smoke from California’s Park ...
Ventilation is a part of structural firefighting tactics, and involves the expulsion of heat and smoke from a burning building, permitting the firefighters to more easily and safely find trapped individuals and attack the fire. It is frequently performed from the outside of a burning building while the fire is being extinguished on the inside.
Video footage of fire containment efforts shows a California Air National Guard plane attempting to suppress the fire by "dropping a line of fire retardant on the Palisades Fire in the mountains ...
Gas flow can be grouped in four regimes: For Kn≤0.001, flow is continuous, and the Navier–Stokes equations are applicable, from 0.001<Kn<0.1, slip flow occurs, from 0.1≤Kn<10, transitional flow occurs and for Kn≥10, free molecular flow occurs. [6] In free molecular flow, the pressure of the remaining gas can be considered as effectively ...
Testing fire hose for thermal resistance to interior heat conditions is not part of the annual testing criteria of fire service hose. Gerald Hughes, Battalion Chief (retired), Chicago FD Some fire district engines have experienced that CAFS-filled hoses have a higher incidence of clogging and decrease in pressure.
