AbstractThis article investigates flame height and axial temperature profile of a buoyant turbulent line-source jet fire plume. Previous correlations have been mainly for axi-symmetrical fire sources or linear pool-type (no initial momentum) fire sources. Experiments were carried out for this study using a 3 mm (width) x 95 mm (length) line-source nozzle with propane as the fuel. Flame heights and axial temperature profiles were measured for different heat release rates. It was found that the flame heights can be well correlated by flame Froude number with a 2/3 power function based on scaling analysis. A global non-dimensional four-regions correlation (continuous flame region, intermittent flame region, line-plume region, and axi-symmetric-plume region) is proposed to characterize the axial temperature profile of a line-source jet fire plume.
