Literature data on buoyant gas turbulent diffusion flames-flame length, momentum flux, and mass entrainment-is interpreted through a simple integral theory for a flame, and the nondimensional analytical frame associated with the theory. In Blake and McDonald [1] the theory is used to analyze data of Becker and Yamazaki [2] for flames in the momentum and buoyancy influenced regimes. It is applied herein to data on buoyancy-dominated flames from Zukoski et al. [3], Cetegen [4], Cetegen et al. [5], Delichatsios and Orloff [6], and Zukoski [7]. In addition to interpreting the data within the context of the theory, this work provides a numerical solution of the theory, and a reformulation of the theory for comparison with semiempirical relations in the literature.
