Study was made to determine flame-spreading characteristics of opposed-jet stabilized flame and their relation to chamber combustion efficiency; tests were conducted in combustion tunnel at atmospheric pressure, using premixed propane and air; chamber combustion efficiency equation based on increase in rate of momentum was used to study variation of chamber combustion efficiency in flame spreading region; efficiency was shown to correlate with fraction of duct cross-sectional area occupied by flame, as well as fraction of inlet mass flow rate which was burning; theory of Miesse correlates with experimental data for certain values of order of reaction and Damkoehler's first ratio.
