Laminar flamelet modelling of turbulent premixed combustion (Q1267167)

We present laminar flamelet method (LFM) for turbulent premixed combustion. Two different approaches are investigated. In the first method, the standard eddy dissipation concept is used as the turbulent combustion model, and the laminar flamelet model is applied as a post-processor for subsequent nitrogen oxide predictions. In the second approach, however, a higher predictive potential is achieved by employing the LFM as the turbulent combustion model. Predictions are compared with experiments for two different turbulent premixed flame configurations, namely for an essentially parabolic, laboratory flame, and a strongly swirling, recirculating flame of an industrial gas turbine burner.
