Literature data on the length of turbulent diffusion flames is examined for the buoyancy through momentum dominated regimes. This data is interpreted through an ad hoc dimensional analysis where the length scale is the Thring-Newby theoretical lateral flame dimension. The nondimensional flame length is shown to be a function of a density weighted Froude number (inverse Richardson number) and a flame to ambient density ratio. Experimental observations on gas turbulent diffusion flames are combined with data for condensing vapor jets and jets in liquid metal combustion. The latter measurements extend the data base and offer new insights into the mechanisms affecting turbulent diffusion flames.
