Abstract The parametric equations for gas velocities and pressure, in terms of the density ratio and wake width, for a flame spreading in a rectangular duct from a point flameholder, are reviewed. A series solution for the cold gas velocity is proposed, evaluated, and its applicability to parametric values shown. An attempt is made to determine the axial wake spreading rate, through a fluid mechanics approach utilizing the momentum equation and later the moment of the momentum equation. Both attempts are unsuccessful, for undetermined reasons. The axial wake spreading rate is then approached, after defining an effective turbulent flame velocity, by equating the rate of disappearance of mass from cold stream with the rate of consumption of mass by the flame. Comparison is then made with a few of the conclusions that have been derived from experimental results.
