title = "Flamelet generated manifolds for partially premixed, highly stretched and non-adiabatic combustion in gas turbines",
abstract = "An extension of the Flamelet Generated Manifold model is presented in this work. Elevated flame stretch rates and heat loss are taken into account without extending the manifold by further dimensions. This is accomplished by modifying the reaction progress source term. The underlying models are based on the analysis of premixed counterow flamelets at various enthalpy levels. Knowledge of flame stretch and heat loss is required as they serve as model inputs. Both quantities are derived from the mean flow in the context of Reynolds-averaged Navier-Stokes simulations. Implementation and testing of the proposed models is accomplished at an atmospheric single burner test rig. The numerically obtained turbulent flame brush is benchmarked regarding position and shape on the basis of experimental OH*-emissivity data. The impact of considering heat loss and stretch is analyzed separately and simultaneously: (1) Considering solely heat loss leads to small alterations as the combustion is slightly damped in the outer shear layer. (2) Taking elevated stretch rates into account has major impact and results in substantial improvement regarding the flame shape. (3) The prediction of the turbulent flame brush only fits the experimental data accurately if both effects are considered.",
