Abstract Flame height and lift-off distance of vertically oriented rectangular source natural gas jet fires with buoyancy-momentum flame Froude number up to 3.06 are investigated by a series of experiments. The jet fires are produced by rectangular equal-area nozzles (314 mm2) with 6 aspect ratios (length to width of the nozzle exit) ranging from 5:1 to 50:1. It is found the flame height (excluding lift-off) gradually decreases as the aspect ratio increases for a given heat release rate due to a...
