Wall flame heights with external radiation
Fire Technology, 1991An existing flame heat transfer fire testing apparatus was used to study the upward flame spread potential of two kinds of wall materials: (1) PMMA (Polymethylmethacrylate) and (2) Douglas Fir Particle Board. PMMA is noncharring whereas Douglas Fir Particle Board is a charring material.

STUDY ON FLAME HEIGHT OF MERGED FLAME FROM MULTIPLE FIRE SOURCES
Combustion Science and Technology, 2004A series of experiments to study merged flame from multiple fire sources was carried out. The porous 15-cm2 burner was used as a unit burner and propane was employed as a fuel.

Tunnelling and Underground Space Technology, 2021
Abstract A series of fire tests was carried out to investigate the diffusion flame characteristics of double fires generated from separated burners in a naturally ventilated tunnel, considering different heat release rates and fire separation distances.

A Physical Model for Flame Height Intermittency
Fire Technology, 2017In this paper, a simple physical model for flame height intermittency in buoyant diffusion flames is proposed. We use dimensional analysis to link existing relations for the pulsation period of diffusion flames and the burnout time of discrete volumes of gaseous fuel. From this analysis, relationships for flame height and intermittency as a function of

Flame height behavior from multi‐fire sources
Fire and Materials, 1993AbstractThe flame height behavior of merged or inclined flames from two rectangular fire sources in a parallel configuration and from three and four circular pools of 120 mm diameter in a symmetrical configuration were studied experimentally. A rectangular gas diffusion burner, 20 mm × 400 mm or 20 mm × 800 mm was used as line fire sources. Propane gas

Turbulent jet diffusion flames: consolidation of flame height data
Combustion and Flame, 1999Literature data on flame heights of turbulent jet diffusion flames are examined in ratios to flame heights of purely buoyant turbulent diffusion flames. The flame height ratio is found to be a function of the gas release momentum in ratio to the momentum generated by a purely buoyant flame.

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.
