1996年1月1日 · The burning rate integral is suggested as a generally applicable measure of local combustion rate. A definition for it, valid in both laminar and turbulent flames, is obtained by explicit consideration of the relationship between the burning rate integral and the total combustion rate of a flame.

2018年10月11日 · Fire intensity describes the combustion process of energy release from forest fuel during various phases of a fire. One of the problems with fire intensity is that it is often used incorrectly to evaluate fire impacts on vegetation, especially when the user restricts its usage to a single measure of energy output (Keeley 2009).

2025年1月31日 · Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. Combustion is one of the most important of chemical reactions and may be considered a culminating step in the oxidation of certain kinds of substances.

Combustion, or burning, [1] 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.

Fire intensity describes the energy released from the fire or characteristics of the fire behavior such as flame length and rate of spread. Fire severity refers to the ecosystem impacts of a fire such as mortality of trees or loss in biodiversity.

Combustion means burning (lat. cum urere-ustus = burn), e.g. burning wood in air, natural gas in air (or CH4/O2/N2 mixtures in general), hydrogen with oxygen (H2/O2 in gaseous or liquid forms, and not only H2 in O2, but O2 in H2), and more bizarre burnings, such as sodium with chlorine (Na(s)/Cl2(g)), aluminium powder with water, magnesium ...

In diffusion combustion of unmixed gases the combustion intensity is limited by the supply of fuel and oxidizer to the reaction zone. The basic task of a theory of diffusion combustion is the determination of the location of the reaction zone and of the flow of fuel and oxidizer into it for a given gas flow field.

It is demonstrated that the combustion mode and combustion intensity can be quantitatively determined by either the statistical mean Sankaran number, Sa, or the volumetric fraction of Sa < 1,...

2025年1月15日 · Considering multiple fires as an entity, the global combustion intensity results from the collective effects of all individual pool fires. The global average mass loss rate is the ratio of the average initial fuel mass of all pool fires to the average burn-out time.

Combustion stability —> The ability of the combustion process to sustain itself in a continuous manner. Combustion stability depends on mass flow rate, combustion volume and pressure along with fuel/air ratio.
