In the first report, a model for the premixed turbulent flame structure was proposed on the basis of recent experimental results and validated by the good agreement of predictions with measurements of the turbulent burning velocities of 16 mixtures. In this report, the turbulent burning velocity derived and all structural parameters were reduced into dimensionless quantities. As a result, all reduced parameters were expressed with only four dimensionless variables : the Reynolds number Re, a Damkohler number Da_η, the Prandtl number and the ratio of the thickness of the reaction zone to that of the preheat zone of an unstrained laminar flamelet. A generalized correlation between the flame structure and burning velocity was thus obtained and shown in Re-Da_η planes as well as S_T/S_<LO>-u'/S_<LO> planes.
