a phenomenon known as flameover is also known by what other term
Rollover
title: Flame text: called cool flames. The phenomenon was discovered by Humphry Davy in 1817. The process depends on a fine balance of temperature and concentration of the reacting mixture, and if conditions are right it can initiate without any external ignition source. Cyclical variations in the balance of chemicals, particularly of intermediate products in the reaction, give oscillations in the flame, with a typical temperature variation of about , or between "cool" and full ignition. Sometimes the variation can lead to an explosion. In the year 2000, experiments by NASA confirmed that gravity plays an indirect role in flame formation and composition. title: Flameout text: Flameout In aviation a flameout refers to the run-down of a jet engine caused by the extinction of the flame in the combustion chamber. It can be caused by a number of factors, including fuel starvation, compressor stall, insufficient oxygen (at high altitudes), foreign object damage (such as caused by birds, hail or volcanic ash), severe inclement weather, mechanical failure and very cold ambient temperatures. A flameout is believed to be most likely to occur when flying through certain weather conditions at a low power setting such as flight idle (e.g. during the descent). These conditions include flight through moderate title: Rollover (fire) text: Rollover (fire) Rollover (also known as flameover) is a stage of a structure fire when fire gases in a room or other enclosed area ignite. Since heated fire gases, the product of pyrolysis, rise to the ceiling, this is where a rollover phenomenon is most often witnessed. Visually, this may be seen as flames "rolling" across the ceiling, radiating outward from the seat of the fire to the extent of gas spread. Rollover is not the same as flashover, although it may precede it, and the terms may be confused. In the case of rollover, only gases present in the title: Flame text: Flame A flame (from Latin "flamma") is the visible, gaseous part of a fire. It is caused by a highly exothermic reaction taking place in a thin zone. Very hot flames are hot enough to have ionized gaseous components of sufficient density to be considered plasma. Color and temperature of a flame are dependent on the type of fuel involved in the combustion, as, for example, when a lighter is held to a candle. The applied heat causes the fuel molecules in the candle wax to vaporize. In this state they can then readily react with oxygen in the air, title: Rollover (fire) text: room, not the room contents, ignite.
