Bunsen burner

A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion.

Burke–Schumann flame

In combustion, a Burke–Schumann flame is a type of diffusion flame, established at the mouth of the two concentric ducts, by issuing fuel and oxidizer from the two region respectively.

Candle

A candle is an ignitable wick embedded in wax, or another flammable solid substance such as tallow, that provides light, and in some cases, a fragrance.

Combustion

Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Diffusion

Diffusion is the net movement of molecules or atoms from a region of high concentration (or high chemical potential) to a region of low concentration (or low chemical potential) as a result of random motion of the molecules or atoms.

Emmons problem

In combustion, Emmons problem describes the flame structure which develops inside the boundary layer, created by a flowing oxidizer stream on flat fuel (solid or liquid) surfaces.

Flame

A flame (from Latin flamma) is the visible, gaseous part of a fire.

Fuel

A fuel is any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work.

Gas lighting

Gas lighting is production of artificial light from combustion of a gaseous fuel, such as hydrogen, methane, carbon monoxide, propane, butane, acetylene, ethylene, or natural gas.

Incandescence

Incandescence is the emission of electromagnetic radiation (including visible light) from a hot body as a result of its temperature.

Liñán's diffusion flame theory

Liñán diffusion flame theory is a theory developed by Amable Liñán in 1974 to explain the diffusion flame structure using activation energy asymptotics and Damköhler number asymptotics.

Micro-g environment

The term micro-g environment (also µg, often referred to by the term microgravity) is more or less a synonym for weightlessness and zero-g, but indicates that g-forces are not quite zero—just very small.

NASA

The National Aeronautics and Space Administration (NASA) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research.

Oxidizing agent

In chemistry, an oxidizing agent (oxidant, oxidizer) is a substance that has the ability to oxidize other substances — in other words to cause them to lose electrons.

Oxidizing and reducing flames

In various burners, the oxidizing flame is the flame produced with an excessive amount of oxygen.

New!!: Diffusion flame and Oxidizing and reducing flames · See more »

Oxy-fuel combustion process

Oxy-fuel combustion is the process of burning a fuel using pure oxygen instead of air as the primary oxidant.

New!!: Diffusion flame and Oxy-fuel combustion process · See more »

Oxygen

Oxygen is a chemical element with symbol O and atomic number 8.

New!!: Diffusion flame and Oxygen · See more »

Premixed flame

A premixed flame is a flame formed under certain conditions during the combustion of a premixed charge (also called pre-mixture) of fuel and oxidiser.

Turbulence

In fluid dynamics, turbulence or turbulent flow is any pattern of fluid motion characterized by chaotic changes in pressure and flow velocity.

New!!: Diffusion flame and Turbulence · See more »

Vaporization

Vaporization (or vapourisation) of an element or compound is a phase transition from the liquid phase to vapor.

New!!: Diffusion flame and Vaporization · See more »

Wax

Waxes are a diverse class of organic compounds that are lipophilic, malleable solids near ambient temperatures.
