TLDR
In this paper, the authors measured the flame length, velocity, temperature, and mass flux for line fires in a very similar manner to axisymmetric systems and found that the air entrainment coefficient for non-reacting, buoyant plume region in the Boussinesq approximation and assuming Gaussian distributions for horizontal velocity and temperature is 0.13.About:

A unified analysis for fire plumes
James G. Quintiere,B.S. Grove +1 more
TL;DR: In this paper, a unified analysis based on an integral approach for fire plumes involving finite axisymmetric and rectangular sources is presented, using Gaussian profiles, obtains the best fits to experimental data found in the literature.

Effects of low air pressure on radiation-controlled rectangular ethanol and n-heptane pool fires
TL;DR: In this article, the individual and combined influences of low pressure and aspect ratio on burning rate, temperature, puffing frequency, flame height and radiation for the two fuels were interpreted and formulated.

Linking surface-fire behavior, stem heating, and tissue necrosis
A. S. Bova,Matthew B. Dickinson +1 more
TL;DR: Data from 69 experimental, small-plot fires are used to describe relationships among fire intensity, bark-surface heat flux, and depth of necrosis in stem tissue for red maple and chestnut oak and may be useful for estimating tree mortality resulting from prescribed fires.

Predicting heat fluxes received by horizontal targets from two buoyant turbulent diffusion flames of propane burning in still air
TL;DR: In this paper, two identical square gas burners with side length of 15 cm were used as the fire sources with propane burning in still air to estimate the heat fluxes received by horizontal targets from two buoyant turbulent diffusion flames.

Fire eruption through intensity and spread rate interaction mediated by flow attachment
John W. Dold,A. Zinoviev +1 more
TL;DR: In this paper, the physical interactions that give rise to either form of behaviour are investigated by way of a mathematical model, in which different expressions for the rate of feedback from intensity into spread-rate are found to identify a threshold between eruptive and stable spread of a line fire.

Entrainment in fire plumes.
TL;DR: In this paper, a new technique for measurement of mass flow rates in buoyant fire plumes is described, and the characteristics of 10 - 200 k W methane diffusion flames stabilized on porous-bed-burners of 0.10 - 0.50 m dia.

Gravitational Convection from a Boundary Source
TL;DR: In this paper, the mean patterns of free convection from a line source and a point source are presented without regard to the specific means by which the gravitational action is produced, and derived functional relationships are then verified and completed through use of velocity and temperature measurements above sources of heat, the generalized form of the results permitting characteristics of the mean flow to be determined over a considerable range of primary variables.

The size of flames from natural fires
TL;DR: In this article, the entrainment of air into a turbulent flame was investigated in terms of both a dimensional analysis and the entrainedness of air to the turbulent flame, and the effects of wind on such flames were also reported.
