摘要: This 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 sources or linear pool-type (no initial momentum) sources. Experiments were carried out this study using 3 mm (width) x 95 (length) nozzle with propane as the fuel. Flame heights profiles measured different heat release rates. It was found that can be well correlated by Froude number 2/3 power function based on scaling analysis. A global non-dimensional four-regions correlation (continuous region, intermittent line-plume axi-symmetric-plume region) is proposed to characterize
