  2. Fire Dynamics Simulator - Wikipedia

    en.wikipedia.org/wiki/Fire_Dynamics_Simulator

    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.

  3. Astronomical spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Astronomical_spectroscopy

    The Star-Spectroscope of the Lick Observatory in 1898. Designed by James Keeler and constructed by John Brashear.. Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, ultraviolet, X-ray, infrared and radio waves that radiate from stars and other celestial objects.

  4. Kugelblitz (astrophysics) - Wikipedia

    en.wikipedia.org/wiki/Kugelblitz_(astrophysics)

    It is a concentration of heat, light or radiation so intense that its energy forms an event horizon and becomes self-trapped. In other words, if enough radiation is aimed into a region of space, the concentration of energy can warp spacetime so much that it creates a black hole.

  5. Theoretical astronomy - Wikipedia

    en.wikipedia.org/wiki/Theoretical_astronomy

    Theoretical astronomy is the use of analytical and computational models based on principles from physics and chemistry to describe and explain astronomical objects and astronomical phenomena. Theorists in astronomy endeavor to create theoretical models and from the results predict observational consequences of those models.

  6. Heat and smoke vent - Wikipedia

    en.wikipedia.org/wiki/Heat_and_smoke_vent

    The majority of guidance available for design of heat and smoke building vents installed in buildings is restricted to nonsprinklered, single-story buildings. [4] This is partly a historical consequence of the installation of heat and smoke vents following the August 1953 General Motors, Livonia, MI major fire in a nonsprinklered manufacturing facility which effectively stopped the production ...

    And with more intense fire activity expected in the years ahead, the threat of smoke grows in kind. "Like extreme heat, smoke from wildfires is also a natural catastrophe that is becoming more ...

  8. Check your air filters. The U.S. Environmental Protection Agency says filters should be checked daily during a wildfire as the smoke can quickly clog the filter with particulate matter. When the ...

    en.wikipedia.org/wiki/Thermal_Micrometeoroid_Garment

    Cross-section of layers in space suit construction. An (Integrated) Thermal Micrometeoroid Garment (TMG or ITMG) is the outer layer of a space suit.The TMG has three functions: to insulate the suit occupant and prevent heat loss, to shield the occupant from harmful solar radiation, and to protect the astronaut from micrometeoroids and other orbital debris, which could puncture the suit and ...
