Laminar Wake Flame Heights

Journal of Heat Transfer, 1980
One important measure of material fire hazard is the flame height a given polymer produces upon burning in a specified ambience. Six systems are considered here—two fuel geometries: wall-mounted and free standing; and three flow fields: forced, free and mixed-mode.

Experimental study on flame height, gas temperature and oxygen concentration profiles under spray fire scenario in an enclosed compartment

Experimental heat transfer, 2020
Spray fire is one of the most frequent fire accidents in ship engine compartments, drawing much attention to spray fire safety. Currently, a series of spray fire tests was conducted in a 2.0 m (L) × 2.0 m (W) × 1.88 m (H) enclosed compartment ...

Visible Flame Heights of Laminar Coflow Diffusion Flames

Combustion Science and Technology, 1999
Results of experiments are reported for overventilated buoyancy-controlled flames of various fuel mixtures in normal atmospheric air. The fuels studied were C2H6, C2H4, C2H2 and CH4, as well as fixed hydrogen-hydrocarbon mixtures of the first three, to give C2H6+H2, C2H4+H2, C2H2+H2 and C2H2+2H2.

Flame height correlation and upward flame spread modelling

Fire and Materials, 2002
AbstractPrevious work has demonstrated that flame height is one of the two most important parameters determining the rate of vertical flame spread on a wall. Flame spread models rely on empirical flame height correlations of the form Xf=KQ̇′n, but there have been no carefully controlled experiments designed to establish the validity of such ...

Wall flame heights with external radiation

Fire Technology, 1991
An 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, 2004
A 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.

Corrigendum to: Interdependencies between flame length and fireline intensity in predicting crown fire initiation and crown scorch height

International journal of wildland fire, 2021
This state-of-knowledge review examines some of the underlying assumptions and limitations associated with the inter-relationships among four widely used descriptors of surface fire behaviour and post-fire impacts in wildland fire science and management,

Flame height behavior from multi‐fire sources

Fire and Materials, 1993
AbstractThe 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

Dependence of Soot Primary Particle Size on the Height above a Burner in Target Ethylene/air Premixed Flame

Combustion Science and Technology, 2021
McKenna burner providing premixed, laminar, steady flat flame is widely used in the combustion community. The ethylene/air flame with equivalent ratio of 2.34 is considered as one of the target flames for the development and calibration of optical ...

Turbulent jet diffusion flames: consolidation of flame height data

Combustion and Flame, 1999
Literature 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.
