The prediction of flame heights and flame shapes of small fire whirls
Proceedings of the Combustion Institute, 2007Abstract This paper adds vortex flows around Burke–Schumann diffusion flames to predict the flame heights and the flame shapes of small fire whirls. The resulting model matches the measurements of methanol flames in a previous laboratory experiment and the results of numerical calculations in this paper.

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.

Measurement of Flame Height by Image Processing Method
Advanced Materials Research, 2011In order to measure the flame height (Lf), the image processing method was employed. The jet flame image was captured by the common-used digital camera. The resolution (C, with the unit of mm/pixel) of the pixel of the digital camera was calibrated by metric scale.

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.

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.

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.

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.

Lift-off heights in underexpanded natural gas jet flames
Symposium (International) on Combustion, 1989This paper describes an experimental investigation into the lift-off heights of flames stabilized in both subsonic and highly underexpanded natural gas jets. The results for the subsonic natural gas jet flames are compared with existing empirical correlations, where the lift-off height is given as a linear function of exit velocity.
