A substance is characterized by a burn rate vs. pressure chart and burn rate vs temperature chart. Higher burn rate than the speed of sound in the material (usually several km/s): "detonation" A few meters per second: "deflagration" A few centimeters per second: "burn" or "smolder" 0.01 mm/s to 100 mm/s: "decomposing rapidly" to characterise it.
Ethanol burning with its spectrum depicted. In the study of combustion, the adiabatic flame temperature is the temperature reached by a flame under ideal conditions. It is an upper bound of the temperature that is reached in actual processes.

The flame speed is the measured rate of expansion of the flame front in a combustion reaction. Whereas flame velocity is generally used for a fuel, a related term is explosive velocity, which is the same relationship measured for an explosive. Combustion engineers differentiate between the laminar flame speed and turbulent flame speed. Flame ...
˙ is reaction rate, and the temperature subscript u is for unburned, b is for burned and i is for ignition temperature. Laminar flame speed is a property of the mixture (fuel structure, stoichiometry) and thermodynamic conditions upon mixture ignition (pressure, temperature).
Erosive burning (high-velocity flow moving past the propellant). Initial temperature of propellant. In summary, however, most formulations have a burn rate between 1–3 mm/s at STP and 6–12 mm/s at 68 atm. The burn characteristics (such as linear burn rate) are often determined prior to rocket motor firing using a strand burner test. This ...
That's why it's important to understand how to calculate your fat-burning heart rate and then implement this knowledge into your sweat sessions to maximize your results.While calculating your fat ...
According to Matalon–Matkowsky–Clavin–Joulin theory, if and are the laminar burning speed and thickness of a planar flame (and =, / be the corresponding flame residence time with , being the thermal diffusivity in the unburnt gas), then the burning speed for the curved flame with respect to the unburnt gas is given by [6] [page needed]
