Fuel, 2021
Abstract The flame height and lift-off height of the turbulent jet diffusion flame of gas mixture at ambient temperature and pressure were studied. Different diameter nozzles (2, 3 and 4 mm), heat release rates, and concentrations of carbon dioxide (CO2) were considered. The flow rates of propane (C3H8) and CO2 were controlled by two rotameters.

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.

Abstract A “chemical” flame height has been defined from the ratio of CO to CO 2 yields, y CO / y CO 2 , and has been shown to be functionally identical with previous results based on flame luminosity. The chemical flame heights have been determined for propane and acetylene data for fire Froude numbers, Q * , ranging from 0.1 to 60,000.

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.

Visible Flame Heights of Laminar Coflow Diffusion Flames
Combustion Science and Technology, 1999Results 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, 2002AbstractPrevious 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 ...
