A Lagrangian Intermittent Model for Turbulent Combustion; Theoretical Basis and Comparisons with Experiments

  • Conference paper

Abstract

A lagrangian turbulent combustion model in which the assumption of infinitely fast chemistry is relaxed has been developed. The allowance for a full spectrum of turbulent timescales instead of a single mean timescale related to the turbulent field is the main feature of the model. We present first the theoretical basis of the model and discuss on its essential entries which respectively depend on turbulence: a distribution of turbulent timescales, and chemical reactions: a chemical ignition delay. Second, numerical predictions on methane-air turbulent jet diffusion flames are compared with experimental data.
