Abstract

The present study discusses results from a number of DNS simulations of turbulent flame kernels. The description of the chemistry in these calculations was based on the Flamelet Generated Manifolds (FGM) technique. The differences are imposed by varying the turbulence intensity and length scale within the thin reaction zones regime. This results in changes in the flame-turbulence interaction. The goal of the study is to see if the presently used reduced chemistry is able to properly deal with the turbulent modulations defined by stretch and curvature of the local flamelets. Especially the influences of the given turbulence effects to the local mass burning rate is investigated. Also global flame dynamics are described and an interpretation of the latter is given in terms of local quantities.
