A theoretical and experimental study of buoyant, axisymmetric, turbulent, diffusion flames is described. Measurements included profiles of mean velocity, mean temperature and mean concentrations of major species for flames having heat release rates of 1.67 and 8.51 kW. An integral model was developed and calibrated with both present and earlier measurements. Empirical constants account for flow entrainment and rates of fuel consumption. Overall, the integral model provided satisfactory predictions of bulk velocity, temperature and concentrations in both combusting and non‐combusting plumes.
