| description | A method for evaluating burning velocity in premixed turbulent flames stabilized in divergent
mean flows is quantitatively validated using numerical approximations of measured
axial profiles of the mean combustion progress variable, mean and conditioned axial velocities,
and axial turbulent scalar flux, obtained by four research groups from seven different
flames each stabilized in an impinging jet. The method is further substantiated by
analyzing the combustion progress variable balance equation that is yielded by the extended
Zimont model of premixed turbulent combustion. The consistency of the model
with the aforementioned experimental data is also demonstrated. |
