Measuring and interpreting flame height in wildland fires
Fire Technology, 1989Although advanced technologies are available for measuring and sampling fire intensity, their costs, limitations, or complexity often preclude general use in field experiments. The lack of quality measurements exacerbates the task of relating ecological responses directly to the fires that cause them.

Measurements of the Visible Flame Height of a Swirl-Stabilized Kerosene Jet Diffusion Flame
Физика горения и взрыва, 2015An experimental investigation of the structure of a kerosene-based Jet A1 unconfined flame is conducted for different fuel flow rates and momentum flux ratios (MFRs). A pressure swirl atomizer is used to atomize the fuel jet. It is found that the flame height increases with increasing MFR for a fixed fuel flow rate.

Linear flame heights for various fuels
Combustion and Flame, 1964Abstract The flame heights of linear diffusion flames for several different fuels have been correlated with a single parameter derived from a model assuming mixing controlled combustion. The assumptions involved are stated clearly.

Luminous heights of turbulent diffusion flames
Fire Safety Journal, 1983A general analytical relation for predicting mean luminous heights of buoyancy-controlled, turbulent diffusion flames is established. The relationship is based on a plot of experimental flame heights in correlation coordinates proposed previously, including extensive data recently published.

Prediction of the Height of Turbulent Diffusion Buoyant Flames
Combustion Science and Technology, 1970Abstract A mathematical model of a turbulent diffusion buoyant flame based on a number of simplifying assumptions is presented. The model predicts the general characteristics of a free-burning fire in both the region where combustion is occurring and the hot gas plume formed above the combustion section.

Peak gas velocities and flame heights of buoyancy-controlled turbulent diffusion flames
Symposium (International) on Combustion, 1981It is found that a parameter ξ, which is closely related to the local Froude number in a turbulent plume over an axisymmetric fire source, can be considered to be a universal constant throughout the nonreacting plume and, often, even into the intermittent flame region.

Height of Flames Projecting from Compartment Openings
2007External flaming from buildings occurs as a result of a large amount of fuel being available in the room of fire origin in comparison to the amount of ventilation provided. The size of the openings in a compartment affects the amount of oxygen available within the fire room, and hence the amount of combustion that can take place inside.

Fire Plumes, Flame Height, and Air Entrainment
2016Practically all fires go through an important, initial stage in which a coherent, buoyant gas stream rises above a localized volume undergoing combustion into surrounding space of essentially uncontaminated air. This stage begins at ignition, continues through a possible smoldering interval, into a flaming interval, and may be said to end prior to ...
