This paper describes numerical and theoretical analyses of the nonlinear dynamics of harmonically forced, stretch-sensitive premixed flames. A key objective of this work is to analyze the relative contributions of kinematic restoration and flame stretch upon the rate at which wrinkles excited by harmonic forcing are destroyed. The dominant contributors vary with perturbation amplitude, due to the nonlinear character of kinematic restoration processes, stretch sensitivity of the mixture, and spatial location. Typical results illustrating these results are shown using computations, and key dimensionless parameters describing their relative contributions are determined from a 3rd order perturbation analysis.
